I've been pretty frustrated with the iPad stands I've seen. The Apple Smart Cover is clever but leaves the back of the iPad unprotected. Some of the cases that double as stands tend to be a bit tippy, and if you try to type or actively use the screen, they just fall over. I like lots of options for the angle of the screen depending on where I am, but many of the cases don't give you all that many choices.
Enter the Prop 'n Go from Padded Spaces in Seattle. It's a thickly padded case with 14 different screen angles. It's available in Microsuede or what's called Air Mesh. The case is designed to provide excellent airflow, and no matter how you push on the case, it's simply not going to slide around or collapse. The model I tested, the US$49.95 standard setup, contains a pocket you can slip your iPad into or use to store accessories.
The accessory pocket is cleverly designed so your power cords, headphones and so on don't come in contact with your iPad. An upgraded case called the All-in-One ($59.95) includes a strap that turns the case into a backpack. A lite version of Prop 'n Go eliminates the internal storage and drops the cost to $39.95. The cases work with either model of the iPad and would store an e-reader, like a Kindle, if you don't use an iPad.
I reviewed the original iPad stand from Padded Spaces (called the Prop it Up) last year. I liked it a lot, but I thought it was too big. The current model is much smaller in width and designed to fit the iPad dimensions. I think this newer model is a decided improvement over an already good product.
