Mobile tech is still very new, and very green. Fact is, “input” still hasn’t been done right. I could complain about plenty of other things, like the slow speed of wireless, weak battery life, and missing live-synchronization with desktops, but input is really still the biggest issue. The iPhone is good but not great, and the same can be said for the Blackberry. When using a PC, an experienced user doesn’t even think about the keyboard. That has yet to be true on mobile devices. Mobile is still a passive experience, and that’s frustrating because mobility is still centered on Internet access, and the Internet is very much an interactive space.
