That's the case I have with mine, on the whole I like it and feel it's protecting my Zaurus and extending it's lifespan. I would never keep my Z without a case.
The only criticisms I have are minor...
1) The case makes this already slightly thick PDA even thicker, so putting it in some pockets is nigh on impossible.
2) The magnetic press-stud catch should have been on the other piece of leather. Where it is now, when you open up the Zaurus, the strip of leather with the catch on has a tendency to curl over onto the keyboard or screen when the case is open. However, you can fold the case right round and use the catch to hold it in place that way.
All in all, I would recommend this case to a fellow Z owner.
