I will be attending college this fall and I'm looking to switch to my first Apple computer (from my Acer running Vista...bleh). I cannot stand Windows, so basically, just switching to Mac is going to be great. I'm currently looking at the middle type MB w/ 2.0 GHz, 160GB HD, and 2GB DDR3 RAM. I need this computer to easily last 4 years and beyond. First off, is this a good choice to look at, with the intention that I am waiting to buy until after WWDC in a week? Do I need to update the RAM in this MB or any other specs? Should I buy the Apple Care Plan? Also, would it be smarter to purchase the MB from the apple online store, or a place like Best Buy or the apple store itself? Any other advice or comments would be greatly appreciated! Thanks!
