After a couples of years of using PC's i've decided to make the jump. However, I need help deciding which Macbook Pro to get. I currently have a HP Pavilion dv4t, core 2 duo 2.0, 150 gb hd, 4gb ram. I mainly use the computer for school. So, I'm currently torn between the 13 inch 2.26 and 2.53. I want to feel the difference of switching to mac. My HP, is pretty fast, it just has too many bugs. I was thinking of getting the 2.26 and just upgrading the ram to 4gb, but how much better is the 2.53? is it worth the extra 300 bucks? Oh, one more thing, i've only recently heard about SSD and don't know much about it. Is it worth buying? If so, do you know of a place online to buy it cheaper? I don't mind doing the upgrades myself. Thanks alot everyone.
