“Upgrading” from Ubuntu to Windows XP? That is not what I’d call an upgrade. This puts Ubuntu in a really bad light if read by people who don’t know better. This sort of false advertising and misleading the public with opinion rather than fact is pretty bad in this case. I’ll meet you half way on this and won’t say that Ubuntu is an upgrade from Windows (since my personal opinion doesn’t matter here). It’d be more honest if you suggested that Windows is an alternative to Ubuntu, rather than an upgrade.
