I’ve been hauling my Surface RT tablet to the office each day in backpack designed to hold a standard sized 15-inch notebook. This is not the ideal way to carry it during the day to, for example, meetings. After looking around a bit, I decided to buy this bag/sleeve from Amazon for $25.

STM Bags dp-2140-1 Jacket Extra Small Sleeve, Fits Most 11-Inch Screens, Black/Green

The Surface tablet slips in easily and the bag fits over it snugly but allows for easy zipping. This STM bag has both a shoulder strap (removable) and a handle. It also has a small front zippered pocket to carry a few odds and ends (including a phone).

I’m quite pleased with it after using it for about a week. It has a 4.5-star (out of possible 5) average customer rating (24 reivews) on Amazon.
