better solution (Score 1)

This is a decent solution to the problem of having your data universally available (with the associated problem of synchronization if the data has to be edited.)

However, I believe the future might adopt a wholly different type of solution than this networked software- one which does away with network bandwidth or network security concerns. With the advent of small-sized, large storage, and even bootable media, people could probably carry all their data and applications (and operating environment) around with them. It's not too farfetched to be able to interface a single such device to all your PDA, cell phones, digital camera, computers. A partial, but weak implementation of this is found with knoppix+pen drive(only interfaces computers, and has other problems), but I'm sure someone will eventually put together a more universal, elegant, and useful implementation. By the way, this isn't my idea. But I do believe it's the right idea.
