See thats what is tough. I am going into the Apple Store today. I do love the screen, but I HATE that I cant upgrade it and that my hard drive is so small. I dont mind the size but a 15" would be nice. I just think it would be nice also to upgrade RAM at my choosing, and throw in an SSD instead of the disk drive when I want. I really wanted a 15" retina but $500 for the upgrade right now is alot and I can put $200 to the 15" non retina and have the ability to customize it to my liking. Ya know? Ugh. Such a tough decision!

If you can see my reply to Troy that is my reasoning. The power would be nice and a bigger hard drive would be too. I have a 500 GB external but its annoying to take everywhere.
