I have not yet held the iPad yet, but I have already ordered my 64 GB WiFi only iPad. Judging from the pictures, it looks like the body (back) of the device is made from aluminum, like the new Unibody Macs. Can anyone confirm this for me? There also seems to be a small shiny apple in the back of the iPad. What is this made of? Will it scratch easily? And finally, the screen. People have said that the screen is very similar to the iPod and iPhone's screens as in it is like a piece of glass. Can anyone tell me for sure what the screen is like, and whether it will scratch or not if you use it outside of its case? In general, would you say that the iPad needs something more than the Apple case to protect it, such as a screen protector?
