Thanks for the feedback! I hope you get a refurb 2015 soon, sounds like they are selling out rather quickly! I have a fully spec'd out 2013 MBP 15" and the battery last at most 3 hours under an intensive programming load. The cycle count is nearing 1,000. I thought about saving money altogether by replacing the battery / backing up the data on an external hard drive and resetting it to factory. I do like the sleek design on the 2016 model and how light it is. It makes it much easier to throw in my book bag along with my other notes / books.
