Hey All, I purchased a new Macbook Pro 13 2.9 Ghz, 8gb ram/512gb hard on March 12th, 2015. I'm beyond the 14 day return policy but I think I got a lemon. I've had issues with the down arrow key being non responsive as well as the trackpad just stop working. I'd like to swap the unit out for a similar unit but with 16GB ram and pay the extra $200. I use the laptop for work so I can't go without a laptop while the unit is being repaired? What are the odds or getting this done and how should I approach it with the local store? It looks like they don't stock the 16GB models. Thanks.
