What a poorly written and headlined article.

Out of the 8 mobile *development* platforms tested, Android rates the lowest.

You actually have to read the article linked at the bottom of daperls' link to find out that of the 8 platforms tested the lowest 4 are:

Android 23%
QT 58%
Symbian 58% (prior to going back to closed source)
MeeGo 61%

While better than Android, it seems QT and MeeGo have significant room for improvement as well.

I wonder if the report even includes recent events in the MeeGo world, and how the might effect the openess?
