DS got his own computer when he was 2. It is a desktop machine built by us parents a few years prior. At first he mostly used it for playing simulations like Zoo Tycoon. I have kept it off the network so far.
Now he is about to get his first netbook, a hand-me-down x100e. I am going to have to think carefully about whether I net-enable it. I may wind up only letting him use it on the web with supervision. Part of the reason for using the netbook is just to let him camp out on the couch or wherever we are with a computer, and part of it is that it has a good-sized keyboard for him built in (although he now has a very small keyboard for the desktop too, and a little mouse).
