ahh decisions decisions. So i need all of your help picking between the three options! I am selling my unibody macbook just because i need something with an SD card slot for photos because its getting pretty tiresome losing a usb for an adapter. I have an ACD 20" already and thats not going anywhere, and i have my laptop 320gb 7200rpm hdd and 4gb ddr3 ram laying around, so here are my options: 1. mid level 21.5" imac (4gb standard plus my 4gb = 8gb /drool) + a netbook (eee pc or acer aspire one) 2. MBP 13" 2.26ghz base model (cheapest option because i already have all the upgrades) 3. MBP 15" 2.53ghz base model. I am a student, i do play some games: WoW, WC3, L4D, etc. nothing too crazy. i am a comp sci major and do work for a tech blog so multitasking is definitely a must. HELP!!
