Ok... So I was hoping for some opinions from people. I currently have a 15' Mid 2012 MacBook Pro Retina 2.6 Ghz with 16GB of RAM. I now have a few problems with my computer (need new charger, battery, a few pixels are out, cosmetics, etc...), certainly fixable with a cost around $300 for charger and battery but was thinking of making a switch for multiple other reasons too, but am worried about how much performance I might lose. So... I think I may have bought my current computer for, well, no real reason, and spent a ton of cash on it since it was the first of its generation. I primarily use my MacBook pro to browse the internet, watch videos, check email, use transmission for "sharing" with family and friends my "personal" documents, use Office, and maybe a bit of photo stuff with iPhoto. That's pretty much it, I think I've edited two videos in the past 4 years. I'm thinking of switching to a brand new 1.3 Ghz MacBook with 8GB of RAM. I know, a huge change, but I'd love to save the money in comparison to buying a new MacBook pro. I know many people will say just pay the $300 and fix your pro, but I wouldn't mind the extra portability of a 12' with my current job and the screen quality should be just as good, and wouldn't mind having a fresh new computer covered by AppleCare. I also could probably get around $450 - $500 for a online trade in for my current MacBook pro. I guess my biggest concern is how much will my day to day use of my Mac change? Will there be a dramatic difference in anything I do? Anyone else have experience making this type of change? I appreciate the help as I am really on the fence. If anyone really knows what they are talking about, feel free to go into specifics on the exactly technical ramifications of the change. Thanks!
