I've been using Google Wallet for about a year now at Walgreens. Sometimes it works, sometimes it doesn't. When it works, it's cool and cashiers are always impressed and ask me questions.

When it doesn't work, I look like an idiot. I sit there tapping my phone and nothing happens, or it vibrates a little and still nothing happens. And the cashier scowls and says "that never works" and I'm like "it works sometimes" and then I have to pull out my old fashioned card and swipe it while people behind me look at me with much disapproval for holding things up.

Then there's the time when I pull out my phone and it won't work because I don't have a network signal for some reason. I put in my PIN and the little circle thing just keeps spinning, all the while everyone is looking at you like an idiot. So instead I try to pre-enter my PIN before I get to the check out -- which is kind of stupid when you think about it.

Walgreens is the only place I've used it because it's the only place I've gotten it to work. I've seen the Paywave thing at other places but I've tried and never got it to work, along with the "looking like an idiot" problem. So I stopped even trying now.

It's really a big hassle. Hopefully Apple pulls it off better. If they do, they deserve to walk all over Google's implementation. Because frankly it sucks. But I have my doubts because I think it's a terminal/merchant/provider issue and instead of just me looking like an idiot, soon there's going to be a plethora of Apple users holding up lines everywhere tapping their phones trying to pay and holding everyone up when it doesn't work.
