Hey all, Sorry for the vague title. Here's my situation. I have a 15" Macbook Pro Retina fully loaded that I use as my primary office computer. I then have a 12" Macbook for travel. I'm 6'5" 240lbs and the keyboard on the Macbook is just annoying to my big fingers haha. I am thinking about looking at one of the MPB 13" on Groupon to replace the 12" so I can get a better keyboard for myself especially when traveling. My questions are; 1) Does anyone have experience with buying one on Groupon? Any pitfalls I should be aware of? 2) Any potential issues you can think of? The one I'm looking at is the 2013 model, not the 2015 model. The other major reason for this is hookups when I'm on the go without having to get adapters for USB-C.
