I've had my 13" macbook pro (2.26 core 2, 2gb ddr3 ram, 160gb hdd, 9400m) since October and I can't put it down! It's the first computer that I truly enjoyed using. Not only is it blazing fast (super fast start up and shut down, something that I definitely never experienced in the windows world), quiet, and cool, this thing looks and feels sexy. The aluminum unibody macbooks are without a doubt the best constructed laptops out there. They actually feel solid, unlike 99% of the junk out there. Keyboard is extremely fluid. Display is very vibrant. Hinge is surprisingly smooth and I like how it closes almost magnetically. Magsafe adapter is awesome. Slot loading dvd drive is welcome change from the flimsy trays on other laptops. Battery life is fantastic. The black/aluminum contrast looks REALLY stylish and I love how it doesn't show fingerprints, scratches and annoying reflections. And I love, love, LOVE the huge multitouch trackpad. I thought that would be annoying at first, but after getting used to the space and all the multitouch gestures, it's really hard to go back to the ancient mouse pads on other laptops. And the texture is perfect; not too smooth, but not glossy like HP either. Apple is way ahead of the curve here.
I'm really happy with my purchase. At first I thought 2gb wouldn't be enough, but so far it has been plenty for my needs (browsing, email, music, videos). I don't plan to upgrade. I do plan to upgrade the hdd eventually, to a intel ssd, once it's cheap enough. I can't imagine how fast everything will be then. So long as everything continues to work like it is now, I can see myself using this laptop for many years.
