I have some questions that I guess maybe I'm not searching properly to find the answers to. I have a mid 2009 MBP (I believe this was the time period, it was the first unibody pro) that is still performing wonderfully. My wife was very anti-Mac when i bought it. Now she loves and uses it more than I do these days as I can't pry it from her. It was originally a 2gb 250gb model, that I (not the most computer savvy) upgraded to 4gb and a 500gb HD myself. My questions are: If i were to buy a new 13" model for myself today, how is the quality (known issues and whatnot) compared to my 2009 model? What are the main differences (I noticed that the base of the new ones are the same stats as my current) between the two? Are the new ones as easy to update the hardware (10 screws was pretty much the jist of it) as mine? I'm not really sure if I'm missing anything. I would like to buy the base model and upgrade the ram to 8gb and maybe a larger HD through Newegg. Any other information would be greatly appreciated. Thanks. EDIT: also, if i were to select the higher of the 2 13" options, how much difference would i notice between the i5 and i7?
