Applications & Development




Browser (chrome,
firefox, ie, safari etc)
Web 2.0 (social net +
location+context,+secur
e id, plus, cameras:)
Sqlite
Server (but almost
certainly Natted)
Music/film/infotainment



Browser(ditto)
Web 2.0 (social net,
amazon, flickr)
Database (well, modest)
Server (but prob.
Natted)
Documenting (hard to do
without kb)
CAD/Graphics Design
Film/Music post
production
Service Architecture



ID/Personality/
Thinnish Client +
Cloud
SIM and Cellular
Service provider
permits


secure ID and
micropayment




Anonymous (hot
desk) or Office
based desktop
Can have thin client
Client/server or
Cloud
Very little proof of
ID except maybe
xDSL subscriber line
Usage & Abusage




Dataplans inclusive
(except roaming)
To date, lockin
prevents malware
Changing fast
No different in
solution space to
desktop



Corporate free,
home use may be
rate/volume capped
Massive problems
with
worm/virus/adware
botnets etc etc
Expensive Solutions
Cost/Performance/Future



Advert or location or
charge for use of
some service pays
Future device may
“dock” with
kb/display-> no need
for desktop or
laptop
18 month recycle



Subscription or
advert or pay-peruse pays
Future device may
be more games
console (GPU and net
speed/latency
special)
3 year recycle
Convergence Done.

Problems will multiply


Opportunities will multiply


Super-linearly with value
Linearly as incumbents loosen grip
