Ive been reading a lot, and decided on the basics for the new computer, but I have a few questions. First, some background: I got a new job that has me traveling a bit, but normally i leave my computer at home. I do not do anything crazy with it. Maybe play a few games, but that is far from being a primary use case. I am leaning towards 256gb hard drive and 8gb ram because: a) I have a 256gb external where i store pictures and movies b) as I said, I dont do anything crazy enough to warrant 16 gb of ram (or convince me otherwise?) First, and most important What processor should I use? What is the real difference between i5 and i7? Between 2.0, 2.3, 2,4, 2.6, 2.8 ghz? Also a question- what size is good? I am leaning towards 15 in because: a) I leave it at home a lot b) 15in isn't that bad for when i need to travel, as I have grown to understand. c) Watching movies, reading, writing, doing presentations on 15in is better and easier on the eyes than on the 13in The only reason that I see me getting the 13 in is if the size is really that much better, lighter, and does not make a big difference on how i read, write, or watch movies, or play the occasional game. Money is not the main issue, im more concerned with getting the system that is perfect for me. I very much appreciate all of your advice in advance! ---------- Or am I overthinking this, and I should just get a MBA top of the line?
