Weeeeeell, I haven't voted because I've only recently gotten my Pandora to go online, so my usage habits are pretty much set.
I'm still exploring what I can do while connected, but as of yet haven't found any reason to be online while gaming (except for TinyFugue thanks StreaK .
I like the idea, and support it... even though I don't use twitter. And I don't use dosbox enough to qualify as a usefull tester... What I like is the idea of increasing interactivity amongst Pandorians - Having updates of who's playing what when could be interesting... May inspire me to game more, know what I mean?
Actually, what would be really nice would be notifications from the task bar regarding who's playing what or even people posting shouts or status updates. That would be a nifty little app to run when online. Sort of like a Pandora exclusive universal automated messenger system that runs in the background.
