you can bootcamp, but you'll have shitty drivers
Yeah, a battery life hit is the main thing I'd be concerned about.
Still no retina displays on MacBook Airs then? I thought Apple was aggressively migrating everything to include at least a retina option.
I guess it costs them too much. That said, when I've played with the macbooks in stores, the 13" rMBP is only half a pound heavier and a little thicker than the 13" air. It's noticeable, but not a big deal. I'll happily take the rMBP in that case purely for the screen. I wonder how the battery life on the rMBP will be once they put Haswell in it - I'm seriously considering buying one of those.
