On one hand yes, but if you want to save money I would wait until iPad 3.
The Leapster is worth upgrading, with the Leapster 2 you have motion play and a built in camera, so extra bits for them to explore and learn further with.
If you are wondering if the iPad 2's availability effect it's purchase price because you are considering upgrading your iPad but want the best deal, then yes it does.
The main difference between the iPad 1 and 2 is that the iPad 2 is thinner and lighter than the iPad 1. The iPad 2 is also faster than the first iPad and the iPad 2 has front and rear cameras.
ipad 2 is one third thinner than ipad 1 ipad 2 has a dual core 1ghz a5 chip and ipad 1 has a single core 1ghz a4 chip so ipad 2 should have almost twice as much processing power ipad 2 has 2 cameras and ipad 1 doesn't have any cameras
The ipad 1 does not the ipad 2 does.
The iPad 2 and 3 have Cameras! The iPad 1 does not!
Depending on what you are planning to use the iPad for, then yes it can be worth it. However, if you just want the iPad to "have it" then it may not be worth it. If you are on the go and need quick access and like to use your laptop wherever you go, then yes it is worth it.
$200 if first generation, $300 if second (iPad 2).
