I'm currently trying to persuade myself that buying a Macbook Air on my student budget isn't completely ridiculous. I have a mid-2011 27" iMac and i absolutely love it, i just could really use something more portable so i go to the library and actually get some work done! I had a 2008 MBP 15" with 2.93ghz processor and spent a small fortune on it, it was fantastic and was far more powerful that i need (as my 27" is) but with several tabs open browsing and listening to music used to hit painfully hot temperatures (100celcius+) and the heat issue put me off another laptop (after i spilled lemsip all over it!) Basically, i have an obsession with buying Mac's that are too powerful for my needs, i am set on getting 8gb of RAM as i see my use as multitasking but not processor heavy (correct?) but choosing between the standard 1.7GHz i5 and the 2.0GHz i7 is the sticking point, would the i7 run hot? or is the heat problem less noticeable with these newer processors than the older Core 2 Duo? Thanks for reading my ramblings!
