Leo says that while most cameras have rechargable batteries these days, cameras that have disposable batteries are an advantage because he could get the batteries anywhere. It would be great for traveling. He can get rechargeable AAs, but he would need to get the high milliamp batteries for them to last. Eneloop Rechargeables by Sanyo are really good.
Jim also wants to know about those cheap $99 tablets, though. They can be recharged. Leo says they're really cheap and it's a false economy. The cheapest Leo would recommend is the Google Nexus 7 at $249. Wasting $100 is worse than spending $250 for a proper tablet.
