Hello guys! I've been really troubled lately as i'm trying to decide on which laptop to buy. I'll use it for coding/university work, frequently running one VM in parallels (just one though, no need for running 2-3 simultaneously). Other than that, it should constantly also run some background clients, and a firefox with ~40 tabs. Gaming isn't a real need, but being able to run dota2 would be a plus, just in case i start playing again I don't use CAD, photoshop or any other heavy GPU app It'll also be my only laptop which means if i'm out that's the one i will want to carry. I now have only a desktop computer with an amd x4 940, 4gb of ram and a vertex 4 128gb ssd (got an hhd too). When out i use a crappy old asus netbook with single core atom and 1gb of ram. That said, I am buying from a non-appple store country (Greece) and thus looking at ebay prices. I can find the 2.4/8gb/256 13 inch for 1300 euro and the base 15 inch for 1600 euro. If i really stretch my budget i can reach both of them. However if let's say I need to switch them in 2 years, I'd much better throw 1300 rather than 1600 euro. My questions are: Is the performance of the base 15 inch so different from the 13 inch? Is it really worth 300 euro? More importantly, is the base rMBP without a dGPU powerful enough for everyday usage + VM? Could the base 15 inch model become my primary computer in say a year or so? How would the 13 inch perform in the same situation? How well does the 13 inch cope as a coding machine? The screen real estate has been troubling me. Could someone provide some screenshots? How well does it run if you keep one VM open with ~2gb of ram assigned to it? Considering I'll buy from ebay and there's no option of returning if screen is faulty or something (i just have the option of repairing the laptop from apple retailers) what would you do? I know this thread is no unique, but some of the usual policies (return and get the other if it doesn't suit you) do not apply to me unfortunately. I've searched my town but none of the big retailers has a rMBP in stock for me to try Looking forward to your replies guys!
