DeLicious is correct, the 880 is IR. It can be annoying as startup macros can take 20 seconds or so (I tell my wife to point it at the TV and put it on the coffee table until it is done. Of course the 890 is much more expensive as well.
Easy to program and very usable other than that.
I'm heading towards trying the 3400 route with CQC but am a bit far from that at the moment.
