Okay so i am about to get a new laptop because my mom wants me to sell my old desktop. I wanted to get the 13" air initially cause it worked similar to the pro and is much lighter and thinner. However, the 128gb SSD is too small for me. I considered bumping up the ram to 8gb and the SSD to 256gb but that will make it much more expensive than the 13" pro, and if i used the extra money on the 13" pro i could have made it even better than the air. So.. it came to my mind that if i could fork out around $170 (or even less than that since i might have to get an external superdrive if i went with the air) i could get a 15" non-retina macbook pro (base model). I could do with the larger real screen estate since. Furthermore, i'd get a superdrive + 500gb HDD, and though HDD is slower i might be able to upgrade the ram to 8gb and get an SSD in future when prices are lower or when the pro starts slowing down. Also i thought that since i'd be using this laptop for at least 5 years, i should get a more powerful one.. So my point is, should i go for this 15" instead? My problem is mainly the heat of the 15" pro as i heard the bottom can get really HOT, and is it worth the price? I can't possibly do any more upgrades for now for this cause it would be over my budget. it's cool if you guys can suggest some ideas, or list some pros and cons between the air 13" and pro 15"
