Raspberry Pi Sales Approach 4 Million 146
Eben Upton's reboot of the spirit of the BBC Micro in the form of the Raspberry Pi would have been an interesting project even if it had only been useful in the world of education. Upton wanted, after all, to give the kind of hands-on, low-level interaction with computing devices that he saw had gone missing in schools. Plenty of rPis are now in that educational, inspirational role, but it turns out that the world was waiting (or at least ready) for a readily usable, cheap, all-in-one computer, and the Raspberry Pi arrived near the front of a wave that now includes many other options. Sales boomed, and we've mentioned a few of the interesting milestones, like the millionth unit made in the UK and the two-millionth unit overall. Now, according to TechCrunch the Raspberry Pi is getting close to 4 million units sold, having just passed 3.8 million, as reported in a tweet. If you have a Raspberry Pi, what are you using it for now, and what would you like to see tweaked in future versions?

If the computer costs just chump change, who CARES if most of them end up gathering dust? The cost of that is trivial, which the benefit of those that DO get used is substantial.
It's like pencil sharpeners (back before cheap automatic pencils): They spend almost all of their time idle. But they're so cheap that it makes more financial sense to have one in every office than to have one for the company and a department scheduling its time-sharing.
(That analogy was acutally used, to get executives to rent a clue, during the transition from central timesharing systems to ubiquitus desktop machines. When a computer costs several million and needs a clean room and dedicated hierarchy, it makes sense to have one and spend a lot of effort rationing it out. When one costs a thousand bucks it's far cheaper to put them on every desk and leave most of them horribly under-utilized. Such a price drop creates a qualitative change to resource allocation strategies.)

So after that it's just the usual - faster and/or cheaper are always nice.
The only real thing missing is quite hard - an ability to do realtime I/O control. That's not really in the Pi, but the Linux OS. If there were a good realtime option, then the Pi would be an awesome controller (e.g. for 3d printing, CNC, etc.). As it is, you need an Arduino control I/O so you have precise timing, which adds complexity as you have to program two devices to coordinate, which is much harder than one. Not impossible, obviously, but simpler/easier is better.

Nevertheless i'm impressed by the momentum. I also think newer generations might fix the hardware issues they have. But just in my view, just focusing on 'as cheap as possible' was a terrible design decision. Had all hardware be high-end, like USB conforming specs, then it would be golden.

- hacking together a little ncurses dashboard of various engine parameters
- writing a standardized datalogging interface that logged everything, all the time
- interfacing it with analog signals to get more data (wideband o2 sensor input)
- writing a decent datalog analyzer program to make use of the data to better tune the car, to the point of where i could just execute a binary and get new more accurate fueling tables handed to me
if it wasn't for the pi, i never would have learned about all that junk in such detail, and my car wouldn't run so well!
it was full of challenges, limited usb ports, hacking the usb ports so the wireless adaptor wouldn't overload the thermal fuses, the lack of RTC meant logging timestamps could never work properly (used a 'global time index counter' type thing), etc.
