I've used this to buy tickets and it was an incredibly easy process. Really, buying anything with Bitcoin is pleasurable experience... even simply to not be beholden to any bank to send money is amazing.
It's similar to watching only downloaded/purchased content versus watching the TV. Once you're used to having no advertisement, turning the TV on is very awkward with all the publicity.
When using Bitcoin, not having to deal with all the road blocks and fees from banks is quite refreshing. Not having to ask permission to do what you want with your money is great!
You make a good point. It's easy for me to criticize Bitcoin from the standpoint of assuming it is the official currency of some country, or the world's only currency.
However, in so doing I am unintentionally ignoring the much more relevant and likely possibility: that Bitcoin doesn't take over the world, but is simply so easy and useful for the cases you described that it "just" becomes the "Internet's currency".
This softens my criticisms of how a deflationary currency carries risks, since in this scenario Bitcoin is continually being converted to and from other currencies.
I think it likely that this is one of those things that will slowly make the difference, and change people's minds about how financial transactions ought to be.
