Nothing Really New
I'm not seeing anything in Windows 7 (I'm testing the beta) that makes me want to run out and spend perfectly good money on it. An operating systems is merely a platform from which to deploy other tools (programs) and do some useful work.
Just because Microsoft releases a new OS doesn't mean the old one stops working. And, frankly, XP works fine.
If I'm going to shell out money for a new OS and have to go through all nonsense with updates and dealing with programs that won't play nice with the new OS, I at least want some real improvement.
Vista and Windows 7 just seem to be "rearranged" somewhat. It doesn't seem to work any more efficiently.
I have a better idea. Lets all declare a moratorium on new operating systems for several years until the hardware gets so screaming fast that the OS programmers will have a difficult time bogging it down.
It just annoys me that a couple year old computer that is lightning fast running XP is sluggish with Vista and Windows 7. I know the manufacturers are hungry for cash, but that's a pretty poor reason for me to buy stuff that doesn't work as well as the stuff I have now.
