I just picked up my first TAF last weekend.
My wife and I are really enjoying it so far, but it also seems a little too simple and/or redundant. it doesn't surprise me when i hear people say 'it gets old fast' or 'gets the least play out of my collection'. We'll see how I feel about it 6 months from now. FWIW, my first reaction to TZ wasn't great either...but I'm enjoying that pin more and more.
