Hi there! I'm new to this forum and really hope someone can help me out. I've been looking at the Transformer TF700. I've just recently noticed that there are a couple different versions of this tablet, like the "B1" or "C1". I've tried to find what exactly is different between these two over the past week (other than $100 price difference), but failed.. Can anyone let me in on what exactly is different? And in your opinion, is it worth the extra money? Thanks so much and what a great forum! I appreciate all help I get!
