PreacherTom writes "For years 3G, or 'third generation,' denoted some future wireless utopia where voice, data, and video would all merge into a wondrous amalgam, marked by snazzy phones that do everything perfectly — and fast. There is indeed a new wireless utopia, and again, it's about merging voice, data, and all the other stuff at even faster speeds. It is known as High-Speed Downlink Packet Access, or HSDPA, and it has started appearing on wireless networks operated by companies such as Vodaphone in Europe and Cingular Wireless in the U.S. Meanwhile, South Korea's Samsung has even started building HSDPA-ready phones. The technology promises wireless speeds as high as 3.6 Mbps but in practice will be much slower than that — fast enough, though, to make wirelessly surfing the Web and downloading music and video well worth the effort."

Lack of substance (Score:5, Informative)
The article seems information-free, largely hype with no substance, by someone who appears to have limited understanding of the issues. Even Vodafone is spelt incorrectly.
HSDPA is actually just an improved version of W-CDMA, the underlying air-interface standard used by the UMTS and FOMA 3G standards. It's an incremental improvement on W-CDMA, it brings more bandwidth but more importantly it brings lower (sub-100ms round-trip ping) latency. HSUPA is the "next step" from HSDPA (HSDPA concentrates on the downlink, HSUPA combines with HSDPA and improves the uplink) and brings better-than-DSL latency to UMTS.
There's nothing that revolutionary about the whole thing. It's still essentially "3G" (which is mostly a marketing phrase anyway) mobile phone technology. Bandwidth is still limited enough that you'll not see operators marketing it as a true alternative to DSL in the same way as, say, WiMax will be.
The article itself seems a little wierd. It's as if someone just found out about SMS text messaging and is enthused about it. HSDPA isn't new, it's been part of Cingular's UMTS roll-out for the two years or so they've been playing with UMTS. Nor is it significantly better or worse than EVDO revision A, which is being rolled out by Sprint at the moment (though there are advantages in the fact that HSDPA is generally implemented with UMTS at the upper levels, rather than the AMPS-derived upper-level protocols that IS-95/IS-2000 networks like Sprint's use.)

The roaming charges stem from increased competition in the domestic markets pruning the monies raised from a finite number of local subscribers.

HSDPA isn't going to help your EVDO latency. HSDPA is an enhancement to W-CDMA, the air interface system used by UMTS. EVDO is a CDMA2000 standard, CDMA2000 being a competing standard with its own air interface standard.
FWIW, oart of the reason for HSDPA is to lower latency on W-CDMA networks (by optimizing the downlink.) With HSDPA, latency on a UMTS network is about 100ms for a round-trip ping. Add HSUPA (which improves the uplink), and the latency drops to around 10ms.
