For me its lack of desktop applications that may or may not work on the linux distro I decide to use. I the lack of "it just works" is a huge problem. I own a mac, and if I see an application supports apple I can be fairly certain it works with my machine (hopefully my OS version) and it will be easy to install and run. Its fragmentation (so many distos...) that makes the app sales market quite small so businesses can't (won't) make a go of making desktop apps. Use linux servers everyday, its the desktop experience which was never really polished. I do want my next notebook to be a linux box though..
