Unless you go with a flexible material I think you're doomed to it breaking unless you go metal and even then it might bend. My criteria is maybe less stringent. I am only concerned about the item being able to assemble / disassemble over time. To me flexible means it will bend and lose structural integrity over time. I prefer rigid. Maybe that means the wood stand is good enough for me.

Thanks for the offer to help me replace my stand(if that's what you're implying), but its a user issue and I wouldn't even think of asking you to replace it because of something I did. If I break it I'd be happy to buy another one.

If you're taking suggestions...

the only thing I am concerned about is on the thin sliver of wood on the back piece. If you extended the width of the back piece to make that little piece wider I think it'll make it much more durable over time and less likely to break.

Another idea is that I have an Oakley microfiber sunglasses bag which fits perfectly the N900(basically a small rectangular sack). If you design the pieces so that when flat they can piece together to form roughly the rectangle silhouette of the N900 you can put a zipper compartment on the bag where the pieces lie flat. When the N900 is in basically the pieces add just barely any thickness. You don't have to worry about it breaking in your back pocket because if it does your N900 is toast too.

I'm not saying they're good ideas. I'm just sayin... ;-) BTW, don't feel like you need to respond to these. I like making up stupid ideas every once in a while. BTW, if you do decide to make a metal one. I think the side pieces are one notch away from being a bottle opener. Just sayin...
