Well, we are an MS shop at work, and we can't use WinXP forever...
At least we have decided to skip over Vista. But I'll have to keep my 3 year old laptop for at least another year, or I'll be stuck with WinXP for another 3 (we found upgrading Windows entirely on computers to be too much a hassle).
What intrigues me is that they are actually going to release an OS that works on OLDER machines...
They better in today's economy. People getting new computers now won't be happy if they find out that it won't run the new Windows in a year from now...
