It's got a lot of great features, and a lot of potential, but this just doesn't strike me as a finished product.
Part of the problem could be that I had been running several of the betas; it's possible there was old cruft left over that's fscking it up now. If that's the case, though, it should clean that crap out properly, it seems to me.
Oh well. It's still kinda cool, and is the only Outlook-like email client for unix, so that earns it big points. Having the nicely integrated contact list, email, calendar, task list, etc. is a nice thing, and the fact that it'll sync with your palm pilot just makes it that much nicer.
