I think the same thing.

Hi.
I think an FPGA based PDA is a great idea in principal.  I'm glad you've 
published the idea here.  I've been worrying that someone would try to 
patent it.

The only down-side I see is battery life, but compared to running 
Windows CE and driving a bright color display, it's possible that the 
FPGA might not dominate the power draw.  The PDA probably needs to have 
a lithium-ion battery.  Add a small perpheral slot, and you've got a 
pretty flexible system.
