So basically it looks like I am selling off my MBP and iPad to get a maxed out MBA + Thunderbolt Display. I am currently test driving a base 13 inch (will return to Best Buy) and I love it. No slow down from what I do. My question is, is the $100 difference worth it for the 1.8 i7 vs. the 1.7 i5? I am getting a 256GB SSD already, since I need the space. Just want to know your opinions on it. Heating issues, any noticeable performance gains, worth $100 to keep for 1-2 years. Btw, I am buying it on MacMall w/ the AppleInsider discount rather than Apple to save + save on tax. 13" 256 i5 1.7: $1503.49 13" 256 i7 1.8: $1614.08 Thanks for the responses! I do plan to have this as my only computer, and if I need a bit more power for some stuff, I can get a high-end Mac Mini to plug into the Thunderbolt Display. Just want to know if the $110 is worth it.
