I all..... I need advice and some direction from anybody willing to help. I own a 20" IMac 2.4 with 4 GB of RAM. I need to install Windows on my Mac because there is 2 programs I must run for school and they are only compatible with Windows. I plan on installing through Boot Camp which is already on my CPU. I will only run Windows when I need to use these programs, then thats it back to Leopard for all other needs. My question and what I need help with is this..... Should I shell out the cash and go buy a version of Windows XP or Vista to install? Or is it possible to try Windows 7. I dont know a whole lot about Windows 7 except I see a lot of posts here about it on the forums and I thought I read somewhere that is was free. I like free, lol especially if I only need Windows OS for 2 programs that I will run occasionally. I appreciate anyones insight on this and for my particular needs. I am unsure of this stuff and just want to make the right decision... Thankyou so much in advance for your replies!!!
