Win 7 fast success is quite understandable: just like XP did wonders after the appalling Win ME and the excellent, but scary for lusers, Win2000 with SP>=3, Win 7 follows the appalling Vista, so it was as eagerly awaited as XP. Let's just hope that after 2 or 3 SP it will become as good as XP SP2 or SP3, we'll need something at least decent when XP extended support expires in 2014.
