I will say for most home users and some small businesses, upgrading to Windows 7 and getting the hardware and software that are fully designed to run under Windows 7 should be relatively easy. For large businesses, that can be a different story as some may not even want to upgrade (to Windows 7) and just stick with Windows XP and the hardware & software that just worked with XP.

What’s your take on what Garry wrote in his article of sticking with XP in 2010 (and perhaps beyond)?
