My Asus Transformer Infinity TF700T fits in perfectly with or without the keyboard and there's a surprising amount of space for memory sticks, pens and pencils, smartphone, spare pack of cigs, passport etcetera, etcetera. All in all a great convenience for someone who travels as much as I do. It slips nicely under the seat in front on the plane without compromising the space for your feet, so it's handy for picking up and using the tab as soon as the aircrew says it's ok. Seems sturdy enough as long as you don't expect too much from it. I doubt it would save the tablet if I chucked it down the stairs for example, but it certainly protects it well from everyday handling and carrying around. The carrying strap is light but adequately sturdy and easy to adjust for length. Once adjusted it stays adjusted and doesn't steadily "grow" as some do as their adjustment slips with every step!
