Not in my life ! M$ lost me quite a while ago, actually even before Vista, when XP was already growing old in the tooth in 2006.
I'm now a happy Linux user (Arch for my Netbook and Ubuntu on the other 7 machines (Laptops, Desktops and Server) we have in the family of 4).
Windows is relegated to were it belongs : a WinXP Virtualbox image stored on the NAS. This way anyone can boot it up whenever needed ...... which was the last time in February .... go figure.
Sure, I tried the Win7 RC and found it to be better crap than anything seen from M$. But it's still Windows and compared to a real Posix OS such as MacOSX, Linux or any of the BSD flavors : IT'S STILL CRAP!
