Carrying around such a nice little tablet leads to the next issue of finding a suitable case for the Nexus7. Recently, there was a youtube post which showed why you should not get the official Nexus7 case.
The suggested alternative of a "leather" case from ebay is $10 compared to the official case sold at JB Hifi for $25 in strange colours. The problem with the ebay case is that the form factor of the Nexus 7 seems to be lost because the case makes it quite bulky in the end.
There is another case which seems to keep the size down which is currently selling for $US13.99 + shipping as shown below. Oh yeah, its very important that you get a case which has the SMART CASE function which can turn on / unlock your Nexus 7 when you open the case.
