I've always been a PC user, even back to the IBM my dad owns that we played with as children. I had a cream colored exterior, a black screen, and green type....we're talking DOS people. But it had a great game where you were a ship and you tried to drop bombs on submarines, it was the best!
Anyway, through college I used Dell computers and now I have a nifty little HP laptop that recognizes my left thumb print (used for log in), has a touch screen, and even has a screen that folds down so that I can write on it like a notebook!
I just spent a couple hours upgrading from Windows Vista to Windows 7. I didn't have any major complaints about Vista, but I decided to upgrade to 7 when I found out that I could do it for $30! (that is 85% off retail value)
How did I do it? Well, I'm in grad school and I have a functioning email address that ends in ".edu" and that is all it takes. My father-in-law sent along a helpful email with all the information and this link with directions.
So, if you have a .edu address and you'd like to upgrade to Windows 7 for $30, just click the link and be on your way!
