I beg to differ. It is a matter of adjusting your expectations and your IDE layout - like we haven't done that before. In my case I have learned to like and prefer the advantages of wide over tall given a single screen limitation. On a 1920 wide screen it is easy to place two or three editor views side by side in eclipse - useful for example when dealing with multiple related classes like manager, entity and DAO classes for a given "object" in a typical enterprise app. (Just drag the document tab for a class sideways and off the main editor panel). It's not ideal - vertical space is still important - especially with the proliferation XML config files and chatty bean setters and getters, but getting used to using code folding and ouline views helps. In the end, enough that I prefer wide over tall.
(Disclaimer: my 'primary' desktop workstation has three widescreens with one oriented sideways for max vertical scrolling power - I never said I did not like vertical space).
