I had issues with my install all over the place. Just getting over it now and many of my built in peripherals needed new drivers. (Which were extremely hard to find on the Acer support site, ended up finding the acer ftp server from a chat board!)
But after all is said and done it's pretty sweet. If you only have one machine for work though I'd be a bit sketchy, cause it's possible it may take an entire day to get everything working properly. It seems to start up way faster than my XP, and I swear I'm looking at a MAC. From the new explorer windows, to the fonts, everything. Mac has Aqua, now windows has Aero! Original! Still sweet as hell and I like the speech recognition!
