I have a 11" MBA, coming from an 06' MBP 15", and it has been a joy to use since then. for my 15", i have always had it on my desk most of the time except for class / library work in college. the screen was just big enough for my uses. now with the 11", i am very use to the screen, but am considering buying an external monitor, maybe apple keyboard/trackpad, and speakers to double it as a desktop for when i am home (which is a lot now that i am done school). i can get a good cheap external for under $300 (dell u2311h, i think thats the model) so I am considering the buy. do any of you do the desktop set up with your MBA if its your only machine? also, if you do, do you just use the external + MBA combo? or do you buy a separate keyboard, trackpad, and speakers and run clamshell mode? it just would be nice for a little extra real estate from time to time.
