I did that in March of last year. I paid a little over $1600 for a MacBook Pro. It became a real hassle for me to use. I need to have a CAC card reader hooked up so I can read my DOD email. The install for a Mac was a big deal. I never got it done. Then, you use one finger on the mouse pad to do one function, two for another and three for another. You are supposed to be able to tap on the mouse pad to emulate the left click of the mouse, but sometimes you had to push the center of the mouse pad and hear a click before anything would happen. I finally spent just over $300 at Amazon for a Windows 7 machine that immediately recognized my CAC card reader and the operation was familiar and easy for me.
My Mac sold on EBay for $782 last Saturday night. I would advise you to buy a used Mac or you will have to lose a lot of money if you are unhappy with it.
Oops. I forgot to turn off the italics.
What about purging MS 7 and going to Linux?
