Ah hah, I forgot about Fantastical. Looks like it will do the trick for quick entry of reminders which was one of the few features I was missing after Things. (Plus there's a 50%-off sale).
Using an Fn double-tap to dictate makes it Siri-esque, only more reliable :)
With the release of Mountain Lion I am getting along fine with Reminders. I use Fantastical in my menu bar to add things, it's always synced to my phone. Has priority, time & date, and geolocation.
