I hope more companies start using those tricks that let websites resize gracefully on any size screen, so you don't even need a mobile theme. Your layout just adjusts gracefully to the screen.
I expect that things will only improve as more people access the web via mobile devices. I think I use my phone more than a standard computer these days.
We are agreeing, though, yes.
And then the mobile site crashes for whatever reason? Malformed URL? Heck if I know. I just know I can't get to the website.
It also seems a lot of websites has a "standard" mobile-version (which is basically some iPhone-app like standard theme) which also always crashes when visited. Might be a WP-plugin, but I'm honestly not sure. 90% of the time though, it crashes and it wont let you go to the original web-page either.
Really. Until the web gets better at dealing with mobile devices, you will see applications like this being popular.
