Battery life is hitting a full work day for me. I stay logged onto MSN, AIM and GTalk all day and I only have battery life problems when forgetting to turn the FM transmitter off. The ovi maps app kinda sucks, but using google maps from the browser is just fine.The 3G is working nicely on t-mo US with the $10/month plan.
I have a feeling that a lot of the '300' (Why do I keep wanting to scream, "This is Sparta!"?) hang out more on IRC (freenode/#maemo) than on this forum. That will probably change a bit once some of the pre-launch insanity/boredom dies down here, and the the signal/noise ratio gets a little better.
