As awesome as that looks, I probably would not get it if it connected into compact flash. My compact flash slot is used by many other things and this would be handy for watching movies, browsing the web with, or being able to read the terminal easier when I SSH into other computers. Unfortunately, for all those things, the compact flash slow requires other devices in it.
As well, it says it has no external power supply, so I wonder how much it'd draw from the battery.
Regardless, looks very awesome and if they could figure out some other input method (Sharp serial port?) I'd purchase.
