Hello
I absolutely believe that a Mac is a MUCH better computer as opposed to a Windows computer.
I bought this laptop only 3 years ago and I have to replace it as it is dying a slow and painful death, while my son's friend purchased a mac (or had one given to him) when he was 14, he is now 24 and that Mac is still going strong.
There are many programs that are Mac compatible, any reputable program will be. There are no virus', or very few if any. It is much more difficult to get a virus on a Mac. The speed on a Mac is much faster than any other windows computer.
Perhaps I am biased, however I am getting an iMac (a desktop) to replace this laptop. If I were to get a windows PC with the same features, they would be close in cost.
Something that I would suggest you do, is go to your local computer sales place (Future Shop, Staples or what ever) and try out the new Windows 8! Don't get me started on Windows 8!
My husband is going to get a mac as well, and he works with computers!
