ok so I am planning to buy a new rMBP for the first time;I am from the UK and I will be starting very important work called A levels (if you're from the US, its like high school to get into university, I have been using Windows for a very long time, and I find that Windows doesn't have rich approachable educational apps, so this is my reason to change to Mac OS X
.
I have looked all over the Internet for which processor is better (comparing performance and battery life); but I am still confused whether to get a i5 or an i7. and the final thing, is the default 128GB SSD enough for everyday average use?
this is also my first thread.
