Situation here. I've never had a mac, and am considering the refreshed rMBP 13" as my first.
My problem is that I only get to go into a city that has an apple store every other weekend, and since I've never really handled a mac with the intention of buying, I'd really like to get a thorough grasp of it before dropping my $$$.
How soon after announcement are floor models available? I'm also probably going to have to custom order online and have it shipped to the store. Darn, this will be almost a month of waiting after release
(also there was little to no discussion of having more than 8GB of ram on the 13" model, I hope this comes true)
