Nvidia is betting a big part of its future on boosting graphics performance in fit-in-your-pocket mobile internet devices (MIDs). iPhone-style devices with Nvdia's APX 2500 system-on-a-chip--due late this year and next year--incorporate most of the functionality of a PC.
On a somewhat related topic, Google keeps perfecting cloud-to-cloud communications. This time it's multi-size embedded presentations. And you can add youtube videos too. Pretty cool. I would probably start using the technology in class this summer, if youtube/docs allowed me to insert snippets of videos, rather than the whole video stream.
In any case, this approach is a sure sign of a potential ms office killer. It offers a combination of a new technology and a new application. Quite a good bet.
