I'm sorry, I stopped reading as soon as you said "Mac". . . .
I'm kidding, I'm kidding! Don't send the kill-squad. Man, you Mac users are sooo touchy.
Seriously Cynthia, a second opinion may be in order. If not, let me ask the obvious question . . . do you NEED a laptop? For computing, a laptop is a compromise form factor, a tablet is worse, your phone worst of all. If you are willing to deal with the limitation of a laptop due to a real need for portability, Macs are a bit pricey. If you are a 6 year Mac user though, are you sure you want to make the switch to an UX based (yes I know Macs now run an UX) or Microsoft system? I use several different operating systems at work and am fairly agnostic; they each run the applications required for their function. At home or on my laptops at work I primarily prefer Windows 7 (yes, I actually said that) since so much of business and the general connected world caters to those products; for better or worse. If you go the Microsoft route, I find going through the "business" vertical of a manufacturer gives me a better and more flexible product range. You also aren't saddled with Windows 8 if you buy a "computer" instead of "consumer electronics". Good luck on your hunt.
P.s. My i7 desktop with all the goodies was less than half of what my primary laptop at work cost. I'm just sayin' . . . .
