I've spent awhile trying to research this stuff to no avail, so hopefully you guys on here can answer a few questions I have. I have bought a August 2009 macbook pro since I need a laptop and will be picking it up on Saturday. I was planning to wait to get the new macbook pro's in the next few months when they are announced, so I'm planning to sell this one once those are announced. (I bought for $650, planning to sell for between $500-600). Alternatively, if the one I am buying fits my needs I may just wait until the new macbooks are announced in 2012. I've found a good deal on ram and a new hard drive in Kijij. The current macbook has 2gb ram and a 160gb hard drive. The deal on kijiji is 4gb (2x 2gb) and a 250gb hard drive for $100. 1) Will "2x 2gb ram modules DDR3 1066 - SD ram" work in an August 2009 Macbook pro? 2) Will the performance increase be worth the cost? 3) Will the increase and ram and hard drive increase my selling price proportionately? I'm new to macs and would appreciate any help. Thanks!!
