Here is a review of the NTFS-3G file system for Mac OS X (or your favorite UNIX-like system). Haven’t tried it myself, but it seems like it might be a useful way to migrate your old Windows files to a Mac … if you were to get a Mac.
A very useful utility for the Mac is NTFS-3G. It’s a peculiar name. Anyway, the latest version installs very simply (automatically installs the required “MacFUSE” without needing a separate download/install), and works straight away.
