Windows 7 ships today, and it's a whopper of a service pack for Vista. It's such a major improvement that Windows users will need to perform a
clean install to upgrade from Vista or XP. Windows 7 is totally worth it for Vista users. XP people will probably want to get a more powerful PC
or Mac to actually run it. Apple
announced new hardware on Tuesday that should run Windows 7 well—plus Macs are the only personal computers that can also run
Snow Leopard. Best of all, your local
Apple Store can transfer all of your files from your old PC!
