Hi Leslie!
Why anyone would change over to Windows 7 is beyond me. Just trying to get all the software and hardware to work with this new operating system is daunting. I do have to admit, though, that when my son's computer using Windows Vista got hit 2 weeks ago by the tough AV Trojan, just going into safe mode and running ASC ("advanced system care," free, CNET) got it eradicated in mere minutes. With Win XP it took me days trying to fix my sister's laptop.
But I too love the venerable Win XP and it supposedly will be supported through 2014 so we're safe for the time being.
