Latest Technology I've discovered

So my husband is really into all the lastest mac stuff out there and he showed me something this past week that I thought was really cool. It's called the Ipad; basically it's a beefed up version of th iphone mixed with a computer. It is about a ten inch touch panel screen. It gives you the ability to buy books and read them straight from the ipad; which is perfect for teaching in the class room. It could also be really good for college students becasue it will give everyone the opportunity to just buy their books electronically using this as a tool. And hopefully the prices for text books will be cheaper than at the book store. This seems like a really good resource for college aged people.
