iPad three is coming out in two months. Sometime in April. There are no official announcements but all the clues are there. I would wait until then if you were gonna get an iPad. A really interesting upgrade in the iPad 3 is the retina display as it will be double the resolution of the current iPad2 and there are also talk that the iPad3 will now be LTE 4G capable. http://funadvice.com/r/15o6bjl0m9i
Here are the costs for the different models: 16GB = $499 32GB = $599 64GB = $699
And if you want to access the Wi-Fi + 3G, then: 16GB = $629 32GB = $729 64GB = $829

Prices for the iPad 2 will come down when the iPad 3 comes out around March-April.
3 times as much as a mp3 player with all the same features
Depends on the model. Go to Mac for exact prices.
