I've been doing a lot of reading throughout this forum, and I can honestly say that I don't understand what you guys are up to. It seems like a lot of people (here, anyway) are buying the Aspire One (which comes with an OS pre-installed) and then nuking the entire system to put something else on. Now I can understand if you want Vista, you need to wipe the hard drive clean and install Vista yourself. But what's up with this? Why buy the XP version of the Aspire One, delete the OS, and then reinstall the exact same OS? o.O If you bought your Aspire One with Linux pre-installed and you want XP, why didn't you just buy the XP version? It seems that a lot of people are having problems after formatting the hard drive and then blaming the problems on the Aspire One itself. Take it from me, I heard from the guy at theacerguy.com that the Aspire One is a "closed system" and that you cannot install another OS on it. For those who have managed to install another OS, maybe this is why you're having all the problems? I don't know what the truth to the "closed system" statement it but, meh. Don't understand... I bought my Aspire One with XP, and that's what I wanted. I can't see myself ever needing to format. At the most, I might need to restore to factory settings, but then again, I also have a backup created by Acronis 11.
