If you like your XP, you can keep your XP...............
LOL!
I've been running XP since the SP1 days of late 2002. Updated to SP2 in late 2004 to get some of the Wi-Fi enhancements. Would still be there if TurboTax had not insisted on SP3, installed in early 2009. SP3 was really worth it.
I understand MSFT makes money by selling software. But they have to offer real value to get existing users to upgrade. In my case (Win XP SP3 and Office 2000). MSFT has never given me a good reason to upgrade. There are lots of features and bell and whistles in XP and Office 2000 that I never use. So why should I upgrade?
Having said that, I may update to Win 7 Pro one of these days just for kicks. There are really few differences between XP and Win 7.
Of course, it's different strokes for different folks and YMMV.
