I am quite happy with the Tucano case I picked up. Good protection, cable pocket, and can be configured as 'picture frame' or 'desk wedge' easily. Navigo for 10" tablet PC
I kind of like the last one...however, though it is said to be compatible with the iconia a510, the picture suggests that it might not. I´ve seen one of this in the ipad and think it´s pretty cool how you are able to rotate it from landscape to portrait. Hope we can be completely sure that it suits the new iconia.
I bought one of the MiTAB cases when I got the Acer, which was the day the Acer was released, and there weren't any other cases available. Waited almost a month for it and was sorely disappointed - but you do get what you pay for. Bought the Moku case from Amagon, mainly because I have one that is similiar for my Samsung Tab, and knew what I was getting. The Moku works great. It is very similiar to the Blurex case, and I already knew the quality of the Moku.
