I "downsized" from a full size iPad in favor of the iPad mini, because it's a pleasure to carry around the mini compared to the somewhat burdensome iPad. But when I added a case to my mini, it became bulky again.
I still prefer a case to protect my valuable device from scratches, but also for comfort and style. Thankfully, the folks at Kavaj have created a set of luxurious cases that add minimal bulk yet perform admirably. Because they use high quality leather, each case is unique and may take some time to stretch and adjust to fit the iPad mini precisely, allowing for the power button to work, for example.
