Lend your voice to Google Mobile's development4
This page is bound to be a vital source of information for the company and with over 60,000 votes already tallied it is proving to be popular. Now all that's left is for Google to take action based on the ideas, which judging by the amount of software still left in Beta (Gmail for example), it looks like they have their hands full already. Hopefully we'll see the emergence of some new ideas from this forum that really boost productivity.
If you've been looking for a place to vent frustration of profess immense admiration for what the developers have been doing, head over to http://productideas.appspot.com/ and help make Google Mobile a better place.
