I still use mine, though it's slowly dying - it requires frequent calibration. I use it mainly with the keyboard to take sermon notes in church.
If delicious will come back up, there are some Newton links that still work on that. I haven't gone looking at software in ages because I don't have anything slow enough running Windows to talk to it. There is some Linux support, notable a package transferrer and a front-end to Sloup, a neat program that lets you rummage inside the Newton's storage databases.
