Can you really put this together?  Who makes the motherboard?  What makes

This is a weak link.  I've heard nasty things about latency over
cell-modem.  I wouldn't want to rely on a telnet link to do actual work if
the latency numbers I got (long since gone from my memory) are right.

What's wrong with putting in a small harddrive and having a real computer?
Battery weight?
