Thanks to an educational discount I can leverage from my brother along with an open-box deal at my local Best Buy (like new, has 2 cycles on it), which 13" Retina MacBook Pro is the better buy? Each one is about $1200. 2013 (early) rMBP 13" ME662LL/A $1214.99 Best Buy (Open Box) i5 2.6 GHz Ivy Bridge Intel HD 4000 Graphics 8 GB RAM 256 GB SSD 7-hour battery (per Apple) 2013 (late) rMBP 13" ME864LL/A $1199.00 Apple (w/education discount) i5 2.4 GHz Haswell Intel HD 5100 Iris Graphics 4 GB RAM 128 GB SSD 9-hour battery (per Apple) Basically, it's a trade-off of the older model with 2x RAM and 2x SSD storage vs the newer model with newer chipset, graphics, and a longer lasting battery. Of these 2, which do you think is the better buy? Thanks!
