I hear you on this... the last time I smoked a butt I had guests over though so the audio alerts on the 733 when thresholds were exceeded was helpful and kept me from obsessively looking at the receiver and being rude. But it's definitely too complex to program the 733, I think, and coming from me that's probably meaningful since I'm an IT guy (sys admin/SQL developer) by trade so I'm definitely not afraid to program stuff. :)
I also might get really used to it as I use it more though, so who knows. These days stuff is supposed to be intuitive right out of the box though (think iPhone).
