Mountain Dave's wish list! & RE: [pct-l] camera phones

[calliger at infolane.com (Richard)]

With the right subsampling/compression math 4MB might boil down'
to 2.3 or so without loss of quality.

Sampling is done such that all white areas are not sent for exmaple,
only the coordinates of white areas of the pic..saving a bunch..

I am on the cuttting edge of this in my work-- and we are a **LOT** closer
to it that you'd imagine.

 Mountain Dave's wish list included:

picture phone was also a PDA including altimeter, compass, 
map/guide book data base, pedometer, GPS, diary, watch, worked on AA
batteries and 
weighed only 4 ounces, I would get one

Well for starters: Next gen of cell phones (now actually!!)
will have GPS builtin (under 4 oz!)
and that will give you soon after that is released- an altimeter, compass, 
pedometer and basic watch. Right now you have PDA's with a kinda-sorta-cell 
connection accessory that is soooo close to a cell phone...soon is the operative
keyword here...remember when it was a dream to see a pic on ANY phone, no less
a self-contained battery powered unit-- that was only 3 years ago!
