The slide to the left is from a Morgan Stanley presentation from 2005. They were doing some crystal ball gazing about the wireless internet…
There are two key “?”s on the slide: a killer 3G handset and a killer mobile app.
I think Apple has nailed both: the iPhone and Safari.
The iPhone has gotten loads of coverage, but the services that are popping up in Safari (in the form of widgets currently) seem to be flying under the radar.
See my previous post on Jajah, and then look at Zimbra’s email client and (if you’re running Safari 3 on Windoze or Mac) have a look at the Leaflets demo page.
As I see more widgets being written for Safari, I think this is the real trojan horse…

Killer hardware, killer apps, shame about the service provider (in America at least…)
