I have been running Windows 7 for months now testing it against other custom applications we use. The cost of updating the applications and buying new hardware to fully support Win7 doesn't lend to any ROI to speak of and given the present business climate it doesn't make sense to spend the money on it at the moment. XP Pro will still be the OS of choice for quite a while yet for our business. As far as home use IF you are buying a new pc then that's the only choice of course if you are wanting to stick with Windows. Win7 is Vista as it should have been. More like Vista sp4. Just a tune up, a splash of gas and a re-package using the same kernel. If you run Vista now I wouldn't spend the money on the update personally. I like Microsoft because it puts food on the table.... I still see no huge compelling reason to go to Windows 7. I use Fedora for my personal pc.
