Dropbox: Startup Lessons Learned

I found these examples odd. Yesterday my family was beaming photos and videos from our iPhones to my Apple TV, I listen to music in my car with Rdio every day and there are usually wedding photos up on Facebook before the reception has begun. Granted, Apple TV and Rdio still seem to be early adopter products (for reasons unknown to me as they're both highly polished and easy to use) but this points to the fact that Dropbox will have much stronger competition in solving those everyday problems.
