I have just read about mini PCs (micro-atx/mini-itx, etc) in MicroMart
and apparently there is a pretty cool device that has an IDE connector at one end and a CF slot at the other, so you can use your flash drive as a standard, albeit small, IDE drive! How cool is that! I know booting from a dedicated flash drive would be better, but at least this would possibly bring flash booting to the masses
Anyway, at the time of writing this, the article is not available on the site - it was only published today (Thursday, 24th July, 2003). It will be soon, though.
