Which would be faster or a better deal? The 15" has 16 gb of ram vs 8 for the 13". Only $200 more for the 15"! Though it only has a 256gb SSD. I'd have to move my itunes library to my 2tb seagate portable, which would be no big deal. Also iris pro on the 15. I'm using it for browsing, music ripping and storage, gaming if possible. No video or photo work. Thoughts? I would be very grateful for any input. The larger screen looks pretty attractive, because as a lawyer I'm often looking at a lot of documents. Many thanks!
