If you're after full Google-everything, Google Android is clearly the way to go. They have a very close, Google-supported relationship.

Maemo/Meego isn't targeted at that, and I suspect many of us chose Maemo precisely becuase we wanted to *avoid* too much Google integration. Optional Googly apps on Maemo/Meego would be nice for those who want them, but Google might not support that: It's probably in Google's commercial interests to keep the Maemo/Meego Google experience less good, less well integrated.
