I just love to shop for computers! So far, you're just sticking with a brand? That sure makes things a lot easier, but if you want more details, I can get to that, too.
I'm unashamedly a Mac fan, and will recommended them to you. If you are comfortable with OS X, or even installing Windows yourself, then it should be fine. The internals of all their laptops is admittedly a generation behind (for political reasons more than anything else), but that shouldn't be a huge show-stopper. Knowing your use cases for this machine would help figure that out. I choose Macs for one basic reason: they're pretty. It goes a little deeper than that, but in the end, they function as a cohesive whole that is aesthetically pleasing better than any other brand I now of, and when I'm spending 8+ hours a day on it, it better look pretty. A second owner's perk is the unparalleled customer service. If you intend on keeping the machine past its warranty, AppleCare is a definite recommendation. I wouldn't recommend the 13" MBP over the regular MB, unless you like the metal look better, or need some extra durability; they are functionally equivalent.
At work, we're a completely Lenovo (coming from IBM) shop, and use mostly ThinkPads. They come close to looking perfect (as far as boring black work laptops can), and are very solid. If you're looking for a better Windows experience, that's my recommendation.
Glossy screens hurt my soul, but it's really a personal issue which is largely dependent on where you want to work with it. Forget about working near a window with that mirror!

On the other hand, there are some benefits to how the picture
looks with the gloss. Again up to you, and your use cases.
As I've said, knowing more about what you want to use it for will be the best help!
