There has been some discussion and rumors swirling around about Apple and a tablet PC of some sort. John Gruber discussed it, as did Paul Bucheit, and the comments on Hacker News has some insights too. For the record, here is my prediction, from the software side of view:

A while ago, I wrote Snippits, a Ruby program that performed text expansion, with quite a few useful features. I built is fairly quickly, because I had an itch to scratch: I hated typing the same thing over and over and over. Computers ought to be able to automate common tasks, and they can’t figure out how to do so themselves, we should be able to teach them. At the time, there was nothing that did text replacement on Linux (but several tools for Mac and Windows existed), so I set out to write my own.

I got pretty far - Snippits was functional, stable, and speedy enough to use daily, and I did so. Of course, it could have been more functional, more stable, and more speedy, but it was good enough for me - and, actually, a couple of users. I was proud of how Snippits had helped people, and I enjoyed using it immensely - there is something extremely satisfying to bypassing tedious typing and retyping of your name, address, email, or really, anything, over and over.
