To preface, I was a big fan of Windows XP. When Vista was released, I wanted absolutely nothing to do with it, because I was so satisfied with Windows XP, and didn't want to change. I heard various horror stories about Vista, but didn't have a first hand experience with it. When it was time to get a new machine, I reluctantly agreed to go with Windows 7, seeing how my job requires me to be on the forefront of technology, how would it look to be using an OS three generations old? Boy, am I ever glad I made the switch. The OS is just so much "smarter" than XP, and it really saves me a lot of time. It's a much quicker OS, meaning that it boots up and loads programs much quicker than before. My new machine had comparable specs to the old machine, so I believe it's in part due to the OS that I'm seeing less wait time between program loads. For whatever failures Vista may have brought, I can say that Windows 7 not only corrected the course, but put Microsoft back in front as well they should be.
