hey all i'm currently using a late'08 aluminum MB 13", which is getting quite long in the tooth. It's had a RAM boost to 4gb (small by today's standards) and a samsung 840 SSD thrown in, so its perfectly useful for probably 90% of what i use it for (mostly surfing, email, work laptop) but when i do photo editing, it gets sluggish. thinking of getting a new MBP, and was looking at the refurb store. question i have is what is the diff between the late 2013s and the refreshed mid 2014s? the refurb store has a nice deal - 15" rMBP with i7, 16gb, 512ssd, 750M gfx for 2K, which is considerably cheaper than a similarly configured new one my plan is to also hook it up to an external monitor/kb/mouse to use for photo editing/work is this a good deal? am i missing out on something by going for a late13 vs mid14? TIA!
