Oh sorry, duplicate post.
One more thing. I was running Calibre on my old XP for years (1 GB ram). Yes, very slow. I recently got a windows 7 dell desk top (4 GB ram) for @$250 from the Dell outlet site. Calibre is very fast now! It would be worth it for you to look into getting a new computer just for that.
