Ah well, if you want a really cheap phone only to phone (and maybe SMS) with, that shouldn't be much of a problem.

Openmoko won't have 3G until at least GTA04 (so not next version but the one after the next version).

But if you're like me and seriously considered a device with 3G, PIM, DAP, GPS, DVB-H (ie. something like a N8x, N9x, iPhone, ...) then once you got your 'N900' you won't need this anymore because the only thing phones do better than the NIT is using cellular network to phone (not over IP) because the NIT cannot do this. One could also use their old phone merely for normal phone calls. This assumes VoIP on 'N900' isn't sufficient, and negates Jerome's argument somewhat.

The advantage is that everything is integrated in one device (except for normal phoning over cellular network). It does create a bigger single point of failure. For sure I'd buy a backup battery, hands down.

Hmm, I meant while on the go, I put the NIT in my moneybelt, with the normal protection map provided with it, and put my passport there as well on the side where the screen is. Passport is made of plastic; not a strong metal like iron (although aluminium would be light its usage is questionable?), but it works pretty well for me.

EDIT: Government forces me to always show my passport when a government official asks for it so I always carry my passport with me except when I'm acting like a animal rights activist .
