I bought the iQue, used it a few times, it worked great. Now it doesn't work at all for some reason and I'm too lazy to figure it out and my life has been OK without it. Everybody has their methods and each person should do what works best for them. My approach is to use as few devices as possible (which basically means none) because I don't like having to rely on anything. Bear in mind I'm just a backyarder. If I was competing, catering, etc. it might well be another story altogether.
