Currently I have a 13" Macbook Pro. I bought it because it wasn't so expensive compared to other 13" laptops on the market. However, I've come to the realization that a 13.3" screen is too small for me when I actually have work to do (as opposed to just consuming media). So this time around, I'm going to spring for a 15" Macbook Pro. However, unlike the 13" Macbook Pro, the 15" is a lot more expensive compared to the other 15" laptops on the market. Now my question is, are there any 15" laptops that have similar build quality to the Macbook Pro? I really don't mind Windows 7 or 8 ... I can live without OS X. My primary concern is buying a laptop that will not fall apart within months of use. If I go with the 15" Macbook Pro, I'll be buying the base model and putting in my own RAM and SSD. Can anyone comment on how decent the GPU is?
