There's a whole array of special requests (there's a dedicated thread for those ^^)
- more ports (SB, Ethernet, SATA, expansion slot...)
- more RAM
- ports position
- USB power
- PCB color
It's hard to know which are really important, and which aren't, and the forum is not a very good place to poll users, since most forum users are hackers, and the foundation is targeted at kids and schools. Eben has come out and said VGA is a priority because even though (or because ?) it is becoming obsolete, there's a lot of it around, especially in schools and as second-hand, ultra-cheap stuff that's perfect for the target market. Even though I personally don't give a damn about VGA, I think it makes a lot of sense for the Pi. If I were them, the second generation would add VGA and integrate the UC+PSU inside a (removable for hardware students) keyboard+trackpad/ball combo, old-school style.
What I'm trying to say is: for us hackers, the Pi is a take-it-or-leave-it proposition. The specs for a first generation are set; the second generation is at least 6 months away, and probably won't move "our" way, unless the foundation decides to diversify, which is a remote chance. We should take the limitations of the Pi as a challenge and a source of fun, not whine or argue about them. There's plenty of other computers (efika, slimfit, sheeva plugs...) that can do a lot more for not much more money. Look at the "alternative to Pi" thread: http://www.raspberrypi.org/for.....ostid-8631
