The problem is that some of the handset makers (or carriers) don't seem to have much interest in providing updates. Which does make sense, in that there is no money in it for them. It's hard to see what Google can do about that.
- Ensure raw Android devices are as pleasant to use as Sense and Rachel. This means stock updates will work on any phone, rather than having to wait for Handset manufacturers to port their UIs to new Android releases.
- Ensure that handset makers have updated their existing units before allowing them to provide 'Google experience' prorietary apps (Gmail etc) to them for new devices.
Or are you talking about XDADevelopers?
