Ray Ozzie:

New programming, storage and interaction models will take us places we've not yet imagined. The PC is shifting from tethered personal productivity and document management toward mobile collaborative productivity, interpersonal communications, and media collection sharing & management. The phone is shifting toward mobile interpersonal communications and awareness, coordination and notification, as well as media playback, recording, and "squirting".

Ray's five architectures for mobility.

2. The "Smart Client, Web Services" Model
3. The "Smart Client Messaging" Model
4. The "Smart Client, Replicated Data" Model

In closing...

I believe we're currently in a transition period for personal computing: from a tethered, desk-bound, personal productivity view, to one of highly mobile interpersonal productivity and collaboration, communications, coordination. We're focused right now on devices and networks because we're coming at the problem bottom-up: preoccupied by gizmos and technologies' capabilities rather than focusing on how our lives and businesses and economies and societies will be fundamentally altered.
