I'm tempted by a 11" or 13" Air to replace my 2010 MBP, I'm still deciding whether I'll buy a new laptop this year or maybe wait until next.
So people with the 11", what did you use as a main device before?
I'm thinking the 13" is more appealing, due to the 12 hour battery life, but since the rMBP 13 has the same battery life as the old MacBook Air, I'm tempted to see what the new one would be rated at.
Apple are really spoiling us with all the options.
