Hi everyone,
After debating between the 13" and the 15", I finally just bought my 13" MacBook Pro. It has the 2.53 GHz processor, 4 GB of memory, 250 GB hard drive, 9400M graphics, etc.. Though I would love more screen real estate, portability for me had to take priority.
My last laptop was becoming much too annoying to use, and felt like it would fall apart any second. The unibody design makes this notebook feel so much more sturdier than my previous one. Also, the 6-7 hours of battery life is great (though this is coming from a laptop which ran < 1 minute on its battery)!
This is my first Mac, and I am very happy with it so far.
