Hi, I have been researching in the limited time I have on Windows 7 and it looks pretty good. Both of my home computers are in need of being upgrade or replaced. My brothers are trying to get me to switch to Mac :lick: but I don't know if I want to make that transition. Can I install windows 7 on my current computers to try it out and then when I buy new computer I can stick with 7 there? I have mostly only found information on going from Vista to 7. What kind of hardware and memory do I need to support 7? Thanks.
