Sounds like more bloatware.
If you were to count the lost productivity in trying to get Office 2007 to do even the simplest things and Vista to do anything at all, it is probably in the millions of man hours — not counting the time waiting for that crap to load, much less do something.
I have Vista on my laptop, and I have not had even one problem.
There were problems in the beginning, but now? I think not.
MS had the best thing in the world on its side: 10 years of users being trained in their product and nobody else's. So what do they do? Change it completely! Brilliant! I can't count the times I've been in a meeting going over a document with someone using Office 2007 and them saying "Umm, I can't find the Bold button anymore" and sitting there while we go through multiple menus to figure out that what used to be a single click is now three or four (after you figure out how to do it). A room full of people .... looking for a button ... that used to be on the main tool bar. How much did that cost?
