What do you think is currently broken, or inefficient? As an example, I think that desktop syncing is currently more work than it needs to be and doesn't have a great user experience. I'd like to imagine that I could easily be out and about using a laptop working on a document and downloading files. Then when I get home and switch on my desktop, it boots up to the exact same desktop with the same files I'd just been using. If I take a photo with my iPhone, it'd be good to have that photo automatically on my laptop in the right folder.
I know it's possible at the moment, and Dropbox does an incredible job at syncing folders, but it still seems like there's a huge disconnect between all my different devices. This may well be what Apple's trying to change with iCloud.
I was just wondering what things other HackerNewsers thought was broken (or at least could be improved on)?
