I don’t have kids but for Christmas I will buy an OLPC (One Laptop Per Child) and enable a kid, somewhere, to get one.
Go to Amazon on November the 17th and buy your kids one, it’s less expensive than an Eee PC ($399) and you will buy yourself good Karma.
And it appears that even some adults may like to receive an OLPC for Christmas ;)
I would like to, but for yourself the keyboard is really not well adapted.
If you don’t get one for yourself, you can give one for $199 :)
