Aha, a thread of note. These fusion netbooks are gonna be the death of me!!
Ok, I'll tell you where I am. I saw the Toshiba NB550d which runs the c50 fusion and thought it was a great bit of kit. Good price, solid form factor, nice machine.

Will keep you posted with anymore details or things I find out
