Looking for a new Macbook Pro replacing my 15" mid 2009 2.66 GHz Intel Core 2 Duo model... Love Apple products and only buy a computer pipeline product about every five years I was wondering if people prefer the 15" or 13" rMBP? I like the current 15" model. I mostly use web browsing, photo editing, paper writing, and make presentations. Not much video editing at all. I was thinking of this model- 15" rMBP with 2.2 Ghz Intel i7 16 GB 1600MHz 256 GB or 512 GB SSD (I currently have 320 and don't know about downgrading?) Intel Iris Any recommendations would be really appreciated... Thanks guy.
