Like most people who had any choice, I avoided installing MS Vista. I did download Windows 7 (build 7100 and RC) and have been quite impressed. So in addition to dropping my hard drives and installing SSD’s (which I also recommend) I’m beginning a computer by computer reinstall to Windows 7 (except for my Mac of course). The downside of this wholesale upgrade is reinstalling my apps. Some you cannot avoid, but I found a page that lists a large number of web apps. Very useful. … and the link.
