When Windows Vista was available for download from MS, I immediately loaded it on my Dell D620. What was my first impression of it? I LOVE IT! If you are a Windows XP user, you should have no problem getting around Vista. There are lots of new setting and featuers but most are the same. The OS is pretty stable so far and it has not crashed yet even after trying to install legacy software that is not supported, because Vista won't let you install it. Vista is a major improvement over Windows XP. Comparing Vista to Mac OS X, Vista kicks OS X's ass. I'm in the IT field so I have to embrace Windows and I could accomplish more than on a Mac. OS X is for fruities who barely know how to turn on a computer.  Keep up the good work MSFT. You are keeping me employed.
