Marco Arment writes about his experience using the Retina MacBook Pro while on vacation from his beloved Mac Pro.

I'm dying to get a Retina model Apple computer, but seeing as my 15" MacBook Pro is only a bit more than a year old, it will be a little while. I think it will work out great in the end. By the time I'm ready to pull the trigger, SSD storage in usable capacities will fall drastically in price and the UI lag will disappear.

Progress.
