I got the 900 mah version.  It's longer than I really like.  I just ordered the 650 mah version for using when I go out.  I'm worried that the 900 mah might fall out of my pocket and get lost.  
I love everything else about it. I think I've finally found my perfect battery!
I hadn't heard that batteries that charge through a USB don't last as long. I'm not charging mine that way, I'm plugging the usb cable into a wall adaptor. I hope that makes a difference.
