It certainly isn't called progress...Vista is a real disappointment from Microsoft.
Vista may eventually be the future Windows OS, but it was not ready for prime time when they released it, and certainly isn't worth upgrading from XP to Vista.
Vista is not as good as Windows XP yet, hopefully it will be in the future, and very soon I hope.
Vista:
1) Less compatible than XP, shame on Microsoft.
2) Slower OS than XP, needs tweaks for better speed and driver support.
3) Driver problems - don't get me started there
4) Microsoft should feel embarrassed about the MILLIONS of man hours, and BILLIONS of dollars spent not getting Vista to be better than it was when they released it, several years late.
