I really appreciate the spirit of this post. However, I wouldn't do away with the native apps (yet!). the N800 is very dynamic and eliminating native apps would stunt its potential. Instead, MUCH MORE development of the communication/web apps and a pause on entertainment apps is what i would suggest.
*better browser (mozilla isn't that good, just better than opera)
*mozilla add-ons
*better integration with google (buttons, documents, etc)
*java
*skype + video
*figure out the certificate issues
*easier VPN abilities
i'm sure there are others. the point, i think you are making, is to really ramp up the web apps/web capabilities. NOTE: Archos just went global with their wrecks. the wifi/umpc/ market is growing....
