I saw one in store the other day. The footprint isn't much bigger than my 11" air. The screen is absolutely gorgeous. In terms of design that's the laptop I've been waiting for. Will I wait? Yes. Two reasons:
- My 2011 Air is still plenty good and if it wasn't for my lust for the new it could serve me far longer than 2013
- Despite the amazing design the current 13" rMBP is underspeced. It's something similar to what happened to the 11" air when it was introduced in 2010, nice design with a pokey C2D. Next year Haswell will make the guts a decent match for the exterior. It will be a more balanced laptop.
