I'm soon getting my Aspire One A110, with the pre-installed Linux distro. I was hoping to install XP instead, and to make it as dead simple as possible I was thinking about getting a USB DVD-ROM from eBay. Would this make installation as easy as it would be on any other computer? Or are there issues relating to using an external optical drive? Any features that will need tweaking to make it work in XP? (networking, wifi, sound, graphics) Thanks for any and all help :)
