He gushes about the keyboard as being extremely comfortable. I may have to consider this as an accessory that I purchase.

Also the official Samsung protective case features a material called d3o which stiffens/hardens on impact for increased protection. Here's the official d3o site:

Here's a video on AU discovery channel about d3o: http://www.youtube.com/watch?v=8EBWGbhsuws

Here's a video of someone being whacked on the head and knee with a shovel... Of course, there's d3o armour underneath:
