Okay, so I'm trying to decide which computer I should buy and I thought you guys may be able to help. I can get a 15' Early 2008 Macbook Pro with 2.53GHZ, 4GB Ram, 250HD, and the 512 switchable video card for 950. I would love the big screen but sucky battery and no warranty kinda sucks. On the other hand I could get a new 13' Macbook Pro at Microceneter for 999.99. But with tax thats obviously going to be above 1100. Which is the big draw back for that cause I would like to save cash. Does anyone know how much slower or faster the older pro would be? Thanks for you help!
