M-Commerce: Got any good examples?

I was arguing with a chap last night about the state of M-Commerce. I was extolling the virtues, pointing out just how useful it is — and how huge the market is set to become. 

I pointed to my favourite example: Amazon and shoelaces. I explained that I don’t give a hoot about shopping for shoelaces — I just want
it done. I want them delivered next day and I don’t want to spend more than a jillisecond thinking about it. Life is short. Taking 30 minutes
out of my day to go hunting for shoelaces is a poor use of time. I demonstrated being able to locate and order shoelaces in about 10 seconds with the Amazon mobile app. 

Then I talked about Pizza Express. Then I explained Masabi’s mobile ticketing. Then… 

I ran out of examples. 

I briefly remembered that Ocado in the UK does (or did, in 2009 if memory serves) 7-8% of its whole revenues through mobile. I quoted that. 

The chap wasn’t having any of it, saying that these were just isolated issues of particular need and that in 10 years time we’ll still be
shopping via a ‘proper’ (desktop) computer. 

Setting aside the fact this chap has his head in the sand, I wondered if you had any good examples of mobile commerce that you could tell me
about? Just a sentence or two. I need to bolster my example array beyond just quoting Amazon or eBay stats. 

If you’ve got a second, stick a quick one-liner comment below telling me about your favourite M-Commerce example?
