As the owner of an iPad and a Kindle 2, I can say it's a pretty good option. The battery life is amazing (in another league than even the mighty iPad battery) and it's tiny and now, cheap. Very strong solution for your needs.
The other thing to consider before buying a second iPad is that you're going to probably want the new iPad whenever that comes out (I'm thinking 12-ish months from launch) so hold off now and the Kindle will tide you over. 2 iPads would get used in my house (kids use 'em) but we're waiting for the next one. Some kids have to suffer on iPhones
