Maybe I'm just a curmudgeon, but I have real trouble with the whole Mobile Web idea, at least as far as phones go. Why? For a couple of very simple reasons:
- Tiny Screens - ever tried to read a largish amount of text on a phone? It sucks. A lot.
- Tiny Fonts - see the first point, above
- Typing - Ever tried to enter more than a trivial amount of text on a phone? Sure, it can be done... but it gets very, very tiresome
Yes, I know that lots of people use SMS. I'm completely convinced that most of them will be crippled with carpal tunnel in a few years too. The problem is one of form factor - you want a device small enough to stow in a pocket - and that means that the keyboard will either be tiny (read: painful), or non-existant (i.e., a telephone touchpad - more painful).
John Batelle is all excited about mashups that involve phones. IMHO, the phone is by and large a read-only device. And it pretty much sucks as a read-only device too, unless the amount of text returned is small. Searching for movie listings or restaurants? Useful. Doing serious work? Not so much.
