27" or this!!!!!!!! damnit. if i had a 27" what monitor would i be able to flip vertical next to it?
No LCD aside from some quite rare ones will be wide enough in portrait to display web pages fully.
1440x900 monitors would work, but web pages need at least 1024 pixels of width, and 1440x900 in portrait only provides 900 pixels of width, and is not therefore that fit for browsing.
If you're thinking of a crap 27" that can only do 1920x1080, read this
Don't get one. A 27" is not worth it unless it's 2560x1440.
