Some other poster mentioned a $50/month unlimited plan on GPRS, well, GPRS is really, really slow. UMTS is supposed to be 2 megabit/second, albeit shared with all users in a cell. UMTS cells will however be smaller than conventional GSM cells.
GPRS can be rolled out pretty much instantly using the existing GSM infrastructure. UMTS will need entirely new basestations to put into place. Why build a network with near-100% coverage, if handsets will drop to GSM if necessary? Well, the VERY expensive UMTS licenses require it.
Then comes along wifi.. Speeds of 3 or 10 Mbps. Today. No big network. Free spectrum. Yes, only at hot spots, but where else do you use your laptop? In the mall? In your car? Hardly bloody likely. Hotels, airports, maybe Starbucks. And they ALL have hot spots already! Using the net on a little phone or pda/subnotebook gizmo? You don't need megabits of speed, existing data or GPRS (2.5G) will do.
So 3G is a really big liability. The license is use it or lose it; don't build a network (again, imagine a billion crisp green bills vanishing in thin air) and your other invested billions will never yield any return on investment (a write-off).

But the cellular providers have a big advantage over Metricom, since they can subsidize the buildout of data services on top of their existing voice customers, and they already have the tower permits which they'll need to deploy 2.5G/3G data-- Metricom had to build a data network essentally from scratch, and the process of obtaining the local permits (different in each locality) was a killer right there.
And the big news, T-Mobile has just started an unlimited data GPRS plan, at $20/mo for voice customers with at least a $30/mo voice plan, and $30/mo as a stand-alone offering-- no service commitment, no contract.

But getting soaked on per-byte and per-minute rates isn't the real issue. The bigger issue is that the cellular networks are end-to-end controlled by the telcos. No service flows over their waves or wires without their approval. Nothing happens on "your" handset that they didn't explicitly pre-authorize -- the exact opposite of the Internet.
If you want to experiment with a new idea in networking, and you're on the Internet, just park a machine on the net with an open port, and try it out. You don't have to get anyone's permission.
On the other hand, if you want to try something out on the cellular network, you first have to get "permission" to write software to run on your own damn phone, then you have to get the Service Provider du Jour to agree to send you the bits you're interested in (for a nominal fee, of course, assuming they know what the hell you're talking about at all). For an example of this idiocy, check out the API for BREW (Basic Runtime Environment for Wireless). It's the only API I've ever seen that expressly has a political layer in its networking stack.
802.11b, OTOH, is just Ethernet-like frames over the air (typically used to carry Internet protocol, but can be used for any other Ethernet-y thing). No permission, no politics, no fellating the local telco to give you "permission" to experiment. Just squirt packets out the interface and see what happens. Yeah, it carries data, but where is it written it can't carry voice as well?

Wifi on a cellular scale. (Score:3, Interesting)
1) Tower space is very expensive. The room for antennas is quite limited for new WiFi installation (on the same scale) as 9xxmhz or other cell equipment generally occupies the ideal antenna locations. Additionally the LOS requirements of 2.4+ghz WiFi make this a little bit less ideal than does lower frequency (thus better penetrating) technologies.
The lack of open source or even inexpensive management and network operations software / hardware make it less feasible (at the moment) than cellular. Just the general lack of cheap units with dual radios makes long range roaming fairly impossible. This will change in the short term, provided that WiFi doesn't go the route of cellular and become a per-minute per-packet large-corp-only business.
The real advantages of WiFi come with its robustness as well as its bandwidth potential. Once you start using Technologies Everyone SHOULD use But Don't(tm) like ipsec you start to have somewhat higher bandwidth needs. Because larger bandwidth with present technology =! higher costs (in fact SHOULd equal lower costs if it wasn't for strong telco resistance) little things like crypto and routing overhead should not make a difference. Nor should p2p traffic, streaming, etc.
The BIG advantage of using WiFi or mixed WiFi / hardline service with good QoS and intelligent ToS / cost-based routing / p2p filtering (i.e. slow down foreign packets / encouraging mature protocols (i.e. torrent, edonkey) is that the major costs of P2P become much much easier to swallow. Hint: multicasting p2p over WiFi is *really* efficient. = )
For those out there who have $100K/year jobs -- a economically unsustainable and generally damaging concept in and of itself -- go ahead and blow your packet charges on cellular. Enjoy 19.2k connections.
For those who still have a glimmer of the spirit of WiFi, the spirit of a free internet and people who enjoy being able to downloads hundreds of gigs a month of whatever they please -- WiFi has much, much MUCH more potential.

I will not use an 802.11 hot spot in an airport, for example, because Vision is good enough (10k BYTES/second -- think 2 B-channel ISDN) but I certainly switch to 802.11b when I'm at home.

Telco's move for network control.... (Score:3, Insightful)
I view this move as a means of wresting control for content distribution and access out of the hands of individuals (access point owners) and into the hands of the mega-telcos. This move also makes it easier for General Ashcroft and the 245th lawyer brigade to monitor traffic and intercept whatever they want. It makes it easier for the phone providers to track your usage, thereby creating yet another product for them to sell to marketers. It delivers to them, the means to target advertising to your mobile device. In short, it puts the consumer back into the "cattle shute" of the big ISP's, where everything becomes an adult playpen, sanitized and appropriatly marketed.
Wi-Fi now, is by definition, run by the person who sets up the access point. This person controls whether it is open or encrypted. This person controls who may access it. This person is responsible for what content may or maynot be distributed through their access point. Having this power in the hands of the individual allows for cool things like "wireless communities" and free hotspots. Whatever the individual chooses. If you don't like it, you can set up your own for less than $150.
On the other hand, if the Cell providers can convince enough people to move to their networks, they can become the standard and can dictate terms of "acceptable use" which, without an viable alternative, become a means of "toll booth" and "restriction."
Ask yourself whether the telcos would allow you to set up a wireless server using their network. This can be done now with an access point and some simple gear...I've seen the handheld wireless webserver here on Slashdot before! Do you think the telco's would allow you to set one up for others to access with their phones?....Think again, we've also seen this week how MS and the phone providers are attempting to create new standards for data transmission between wireless devices...why would that be, when MP3's seem to work fine?...It's the same old practice of creating something propriatary to wrest control out of the hands of the consumer, and put it back into it's rightfull hands...the mega-corps.
It's not that I don't like alternatives, I like them a lot, we just need to keep technology open for people to use in any way they deem appropriate. Wi-FI has grown precisely because it put all the power in the hands of the user. We've seen some pretty weird stuff coming out of many of the users too, stuff that the manufacturers never dreamed of. Don't let the Telco's put that back in the bottle.

1. Price
Sending a byte anywhere across my cable modem costs $0.000000019. Sending one across my GPRS cellphone here in Canada costs me 0.00025 per byte, which makes cellular technology 13,421 times more expensive! Yes, thirteen thousand TIMES more expensive. And 3G is not showing signs of being cheaper. The cell companies have billions in licenses to recover. The 13,421 times difference (that is an 1.3 million percent margin) seems like highway robbery to me.
2. "Getting it". The cell companies have shown no sign of getting anything. They appear to think we are still in the circuit switching age, And have you check cell gprs/wap "content"? One line new headliners updated about once every 48 hours, and cost $0.25 to read? Ther should realise they are thyere to connect us to whatever we want to connec to, not to interpret/provide.
No doubt this will all be solved in the end and we will all have long range wireless, but not until the old telecoms guys are all long retired.

There's a bit more to networking than what can be done with even the fanci-schmanciest cellular toybob. Since there won't be any DSL or cable coming in my lifetime into my area, Wifi is about the only other possibility. Cellular network access it WAY pricey even it it would work. No thanks. Cellular may have a place, but that place isn't as a replacement.
Short Answer : It Already Has (Score:3, Insightful)
The hype factor with WiFi is so much higher than cellular and people with Pringles cans get excited and think 802.11 is the answer to everything from national networks to world starvation. 802.11 was an indoor LAN protocol that got stretched beyond what it was intended to do. Sure, 802.16 addresses some of this, but still the frequency allocations and necessary regulatory protection to create a national mobile network with unlicensed technology just isn't there.
802.11 is better suited for hotspots, but remember when Cellular was only for use in vehicles ? Now people use it in place of their home landline phones. Hotspots are merely fads, cellular will stomp on 802.11 hotspots, just watch.
Cellular is a tortoise and WiFi is the hare in the mobile data race. Slow and steady wins this race...
