I've currently got base 13" 2011 MBA, which I find is a great mix between portability and screen size most of the time. However I'm strongly considering buying an external monitor, because I am increasingly finding that there are occasions when I would love a bigger screen for some programming/word processing/light photo editing work at home. Ideally I would just go out and buy a thunderbolt display tomorrow - however my budget is more in the £400 and lower region (although I could be persuaded a bit higher possibly). My requirements aren't very restrictive: 23" and above <£400 Compatible with 2011 MBA Picture looks great! Any advice/guidance would be great. Would love to hear what you guys use as alternatives to the ATD!
