Our family computer is a Windows Vista, while my laptop is a Windows 7 Home Premium Inspiron 15. The laptop will be taken back to Best Buy for repair, though as one of my drivers is going out of whack again. Last time this happened was a few months ago. I'm posting from the Vista.... I don't even know if I can tell too much of a difference between the brands or not... they both seem the same to me, really. Although the graphics do look nicer on the Windows 7, obviously. I mainly use both computers for foruming and gaming, and I use my laptop for foruming, gaming, and for viewing Youtube videos. Family is mostly for foruming and gaming, and my mom uses the family computer since I use the laptop.
