Just wanted to show the cheap but practical "dual option": a rubberized hard case + a 5 USD generic canvas pouch.

The good thing about this combination is that the N900+hardcase nicely fit in the pouch, unlike the customized N900 cases (that are made for a "naked" N900). I put the N900 in with the screen towards my body, so that it is well-protected. I will have to make a small hole in the cover of the pouch so that the earphone will fit through.

I purchased the rubberized hardcase from the internet and the canvas case at a local suitcase-shop (with cheap stuff).

An other advantage is that the canvas pouch doesn't look very fancy (unlike some of the beautiful Noreve cases) so potential thieves are not interested.
