This is similar to something I've had in my mind for a while. Whether it's "cool" or not is for others to decide, but for me it would be useful. For lack of a better name I'll call the app "lifebase".

The app runs whenever you're not using the screen for anything else. You can add notes and jottings and sketches, which get stored chronologically. You can scroll back in time to find old stuff, or you can find old stuff by using powerful search facilities.

But it's also integrated with the rest of the device. Whenever you take photos, mini thumbnails get added automatically. Whenever you travel somewhere, a GPS track of the journey gets added automatically. Whenever you browse the web, a (collapsible) set of thumbnails gets added automatically. Whenever you play some music, a collapsed list of songs played gets added automatically. Any app can submit notifications to add content.

Whenever you have internet access, everything gets uploaded to the cloud and synchronised with your other devices.

Everything is private by default, but you can mark any item as "share with friends" or "share with everyone". Others can then access the shared parts in all kinds of interesting (cool?) ways. Your public articles and sketches become your blog. Your travels can go to twitter ("10.15am - roger arrived at university"). Your friends can play your playlists on their devices. The stuff you share with your friends becomes available to them in an RSS feed.

And at this point I remember that the Nokia 5800 lets you put thumbnails of four of your contacts onto the home screen, each of which can be associated with two RSS feeds, so that you can keep track of what your friends and family are up to.

So the receiving client already exists. We just need the sending client and the cloud storage and processing.

What's my motivation for an app like this? If I want to jot down a piece of information, I don't want to have to open up an application, write something, save it somewhere, remember a filename, then close the application. I just want to put it straight into an app that's running all the time, and whose data I can access from any of my devices, and which can be readily searched and shared.

Roger.
