I wasn't looking for a book-style case for my N800, but a case in which I can slip it in and out. I was looking for something small, form-fitting, and with a side pouch if I wanted to carry headphones, stylus, etc. I think the Waterfield Nintendo DS Lite Case (SFbags) is perfect. For $39, I got the "Black Pattern Nintendo DS Case" which provides adequate protection when I'm carrying it on the DC Metro. To be honest, I think it's a better case than Nokia's included case or "official case."
