I know they are. You used to be able to get 1080p 15" laptops but haven't seen any for a few years now.
The 13" MBP is 1280x800 btw.
You still can, but they have to be higher-end ones (I have a DELL latitude with one for example, and the pixels are slightly too dense imo).
I was referring to the air in my posts, but 1280*800 on 13" is quite a nice pixel density. I wouldn't buy a 13" mbp because of the graphics though personally (£1k on a full sized laptop without discreet graphics lol).
