Yup. They were first and they iterated & made it great. Didn't even have to write an Android version for a while.

When you compare the amount of work required to get a startup off the ground then to what is required now. (dual mobile platforms & web & social) And the total number of apps & services. It's a deluge of information.

Then is there much change to start a service or company these days & see success? Maybe I'm getting too old, but normally I'd be full of ideas. These days I can't think of any.
