Here's my work case:
Coach :: BLEECKER LEGACY LEATHER TABLET PORTFOLIO
A bit pricey, but get compliments on it constantly. It is quite a nice piece of kit, and as a leather guy, can say the leather quality is excellent (I got the mahogany color). The pockets hold my targus stylus, business cards, and iphone - no briefcase needed. I can fit my ipad 3 with the leather smart cover on it into the sleeve, and it holds it snugly. The best case of its type i have seen, highly recommended. if you are looking for a top of the line professional looking protective case for your ipad.
