You're stepping into a crowded elevator, the door closes, and your
wearable (And all your data) go CRUNCH and the pieces fall down the
crack into the elevator shaft.
Maybe a dumb example, but you get the idea.

When I said that your local storage would be a "cache" of your most
frequently used data, I don't mean 8k bytes like an ARM CPU cache.
I mean a few giga-bytes of data.

I guess its really a hybrid compared to the local/remote paradigms.
(I'm an Engineer and always looking for the optimum compromise!)

I don't need to carry every photo that I've ever taken on a camera with
me all the time, but I'd like access to them.
I don't need to carry the source to every program that I've written in
the last 20 years with me, but I'd like access to them.
And I don't need to carry my entire record/CD collection with me, but
I'd like change what songs I have locally.
And I probably want all my e-mails from the last year.

Hitachi claims that by Q2 2003 they will be shipping MMCs with 1 gig
capacity.  We fit an MMC card-connector between the connectors of our 2"
square computers (the MMC slide between the CPU board and the IO board).

You can have a 2" square computer with 1 gigaByte of storage, SVGA video
out, USB ports for Twiddlers and such and 802.11 WiFi for under U$1000-
about next summer (we're working on it now).
And we'll be support CDMA 1x in the near future too!

Is there anyone out there interested in such a beast?
