I'll start with them. I've sold my computer. I have a laptop from work that now handles all my computing needs. I do not miss having to admin several computers. Having only one makes life easier, and if it has to be only one, a laptop is a very good choice, at least for me.
Mobile computing happens to be interesting.
I don't even yearn for new software. With the home computer I lose my TV card, so I've bought a real TV set instead. Should be nicer to watch DVDs on a somewhat larger image than the 10 by 25 centimeter one I had on the monitor. I notice that I've just about stopped reading diary entries on Advogato. This is probably a loss.
