If you haven't heard enough about Microsoft Vista (the latest Windows version released back in January) to make you cling to your XP version for dear life, here's a little more fodder for your fears. Ars Technica (great techie web site, by the way) did an informal experiment on what happens when you upgrade a variety of older PCs with Vista. The surprising part: the fairly new IBM Thinkpad did not fair as well as the five year old desktop for the home user. Sinatra was right. It's just a crazy, cuckoo world.
