I was getting rather nervous about carrying my n800 in the sleeve it came with, especially after it slipped out of there couple of times and got a few nicks and scratches. After looking at quite a few Nintendo DS cases, PSP cases and hard drive cases, I finally settled on proporta case. I did not want a case that made n800 much bigger than it is. I have been happy with proporta case. It did not add much bulk and has provided good protection when I have dropped my n800.
