All About Mobile has a suggestion and proof on how to increase mobile internet usage.
Couldn't that be different if handset manufacturers and telecoms would push now for integrated QR Code readers like in Japan - which increased by factor 3 the mobile internet usage in Japan in 2005?
I agree. Physical world connection (PWC) will play a big role in increasing Avg Rev Per User (ARPU)
The PWC will get adopted much quicker when there's either a "universal" 2d code (Google could do this), or PWC players make their code distinguishable, like ConnexTo has done.
