The X86 4.3 version runs quite well, a few gliches but very fast. It doesn't like Broadcom though, so I use an external Wireless adapter. Can't get Skype and quite a few apps. but it's nice to use I think.
+ Another one if you don't want Windows is the lightweight version of Ubuntu, called Lubuntu, which is quick, but has a very similar layout to Windows.
# Just a bit of an update. I've been testing Lubuntu 13.10 with the latest Chromium, and it's working very well. Very smooth, fast and no problems.
