* freezing irrecoverably when opening the app/going to inbox very often
* losing all the text you've typed when anything causes the textfield to lose focus
* things like gaining network connectivity causing said textfield to lose focus
Perhaps this qualifies as ad hominem, but this experience was biblically awful and from a major software company. Seeing how this new Gmail app is a bunch of Web views and needlessly non-standard widgets (=> part of the worst dredge of apps), it makes me start to feel pretty cynical about their iOS strategy.
Then again, taken the experience using the Android browser while developing mobile websites, maybe it's an institutional inability to develop polished mobile applications.
EDIT: I don't really know why I'm being downvoted for this. Wouldn't you switch apps too if you relied on google voice for your text messages and you couldn't log into it anymore without it instantly crashing?
