Hello, I would want some advice on whether I should make an upgrade or not. I currently have a late 2011 macbook pro 13" 2.4 i5 HD3000 4 in ram (can and would upgrade) 320 HDD in the optical drive bay and a 128 gb OCZ SSD where I keep my OS and my apps. Running quite smooth with benchmarks of 6500 ish. Considered getting an 11" MBA for on the go beginning to do some more work on the go on planes and such. And But with the new upgrades realized it would have better specs than my current so now considering changing my current mac for a 13" MBA i5 with 8 in RAM. Is it worth it? Would it make sense? or am i just greedy??? Thanks in advance for your input.
