If you want the ultimate wife pleaser, you'll spend a little more and buy a Pronto or similar.
Beeing a "real" remote it will function always with no flaws. Anything else is playing with fire.

But adapting the PDA to remote is more fun...you get to keep fiddling around and in the end, even though not perfect, you'll get a good result.
I use both systems, but would never dream of letting my wife use the PDA. When a button 1 out of 20 times doesn't work, you won't mind, but your wife will!
