I set up Windows 7 on a newer high end Dell laptop(latitude D630) today. The plan is to use it for my everyday laptop. I want to see how long I can use the laptop without have to go back to my old one. Day one has been all about installing everything I need. This included firefox, flash, acrobat, filezilla, tweetdeck, and office. The only issue I had was with tweetdeck. I am not sure why, but the adobe air was having trouble installing. It looked like the computer was trying to install adobe air, even though it was already installed.
Day 1 has been almost all positive. I would say it is a huge improvement over vista. over the next few days, I want to make sure to try all of the new features.
