IMHO co-meeting is the best GWave alternative available today. Basically it's an user-friendly version of Apache WiaB. For now it only lacks OpenSocial gadgets but according to a co-meeting developer, they could be added in the near future.
from the same developers "Taskos To Do List", their previous Android app, is IMHO much better: same functions, a more useful widget and the app is much lighter.
That 36% number may be a little high since TNW is considering the Nexus One and Google TV as failures.
The Nexus One has greatly raised the level of high ends Android phones. It was a first attempt for Google to define Hardware in collaboration with manufacturers, and since they now keep doing that on regular basis I would say it was a success.
Google TV initial launch was possibly a failure, but the Honeycomb or Ice Cream Sandwich update will certainly be a re-born and, possibly, a worldwide "second" launch. I think it's too early to judge it.
