I'm in the group who got very dissapointed that the
EFIKA only has USB 1.1.
But how could you possibly be surprised? The MPC5200B is a SoC, and almost all of the Efikas (at least in the first design) features comes from the specs in that SoC. The features of the 5200 are well known, and they are set in stone. The Efika was supposed to be a two chip computer, the 5200 and GFX, with the scope of being as small as possible, as cheap as possible, as low power (as in Watt) as possible, you must keep that in mind!

All the NAS- and other server-
projects I see in the program really need the possibility
to add cheap external USB-harddrives. Connecting it to
12Mbit would be a joke if the product would finalize to
end-users.
If you ask me, it would be a joke to base a NAS on USB harddrives in the first place (and if you want external drives, wouldn't firewire be better anyway?). For a NAS, it would be much better to simply drop the GFX, drop the FPGA, and add a standard SiI0680A "PCI to IDE" chip (or similar) instead. Then you would have a cheap and highly specialized hardware with the possibility of using up to 6 IDE drives, at "real" speed.

USB 2.0 is the standard and it shouldn't be
necessary to use up the only PCI- port for a USB 2.0-card.
The PCI-port is perfect for a WiFi or SATA-card.
You are assuming that the PCI slot will remain in the design? Maybe it will, I don't know, but AFAIK that was put on the board at an early design stage in order to try out different GFX (and other) solutions, for evaluation purpose. AFAIK it was always said that the slot should go away when those things was brought on board the mainboard PCB.
Anyway, the obvious scope of the Efika has always been to build a device that is as *small*, *cheap*, and *energy efficient* as possible. If you just keep adding things to the design, then you would be going in the exact *opposite* direction. I can think of *a lot* of things that I would like to put on that PCB, a USB2 controller is one of them, but there are so many more things if you have a little imagination. But the more you put in, the bigger the board will get, the higher the cost will be, and the higher power consumption you'll get. And everything would have to sit on the same PCI-bus (since the 5200 has only got *one* AFAIK), which wouldn't exactly do wonders for performance. That's why I think a FPGA is a great idea. That too will add cost, size and energy consumption and share the PCI, but the benefits of being able to add such things as extra USB (even USB2 perhaps?), Ethernet, hardware encoders/decoders, you name it, according to the application needs, *without* changing the base mainboard design, outweights the cons IMHO. Far from all applications needs USB2, and for those applications that *don't* need it, it would be a *disadvantage* from the scope of the Efika's Point of View.
