What would you do (Surface)?

I've run into a situation where a company is willing to let me trade in my refurbished Surface RT (64 GB) + $200 for a refurbished 128GB Surface Pro with box, stylus, etc. At first glance this sounds like a good deal. I love the Surface RT hardware itself but the OS is a hair limiting for my taste.

At the same time I've heard that the battery life on the Surface Pro is less than amazing given the i5 CPU inside. But the biggest point of contention for me is that the Surface Pro 2 must be going on sale soon, right? Given how most companies still have the SP2 and SP3 priced nearly identical, I'd imagine that the SP2 price will be cut once the SP3 is actually on store shelves.

Advice please, oh fellow tribe members!
