Ok guys, I own a Mid-2012 MBP 13.3" with a 2.5GHz processor with 4GB RAM and a self installed 480GB SSD that is about 3 years old. I am being offered to trade it (With possibly a $100 or maybe just a trade) to a brand new Early-2015 MBA 13.3" 1.6Ghz processor with 8GB RAM and 256GB pcie flash storage. Is this a good deal, or should I just keep what I have got. I don't do any heavy gaming on the device, because I have other devices for that. Pretty much run light programs for college stuff. Thx for your thoughts.
