While I had no problems installing 7 on both my desktop and an old Dell laptop and it is nice to have a fancy screen with all sorts of glizt in it, the main function of an operating system is to have functionality. About 80% of the programs I use no longer work or work with limited functionality. These programs have been tried in compatability mode and XP mode with the same problems appearing. This looks like a painted over Vista with the same if not more problems that Vista did when it was first released.
