Fan Guide - need help picking format

Looking to pre-order fan guide.
Can anyone provide help on which format to purchase for an Android Tablet?

I see options for everything under the sun except for a general android tablet. I am afraid the Nook Color (a specialized tablet running a modified version of Android) won't be compatible with normal Android tablets.
I have a Motorola Xoom.

Thanks

Do you have any ereader app on your Xoom now? I use kindle on my iPhone and computer (but don't actually own a kindle device).
