Agree that it is really up to the individual to make those cost-benefit decisions.

Maybe I have drunk the kool-aid, but I am warming to the idea of the Maemo phone (if it is indeed a phone). I was initially disappointed about the smaller screen and the fact that it might be phone capable (I use my n800 on planes quite a bit, and some airlines have a "no cellphone use, even in 'flight mode'" policy.)

But, based on the reported specs, the Rover is actually what I've been looking for in a phone: quad-band GSM, T-mobile 3G, nice camera (for a phone). I am hoping that it will be sold unlocked, though.

Anyway, having the phone running Maemo is the ultimate plus, since I'm used to it and hopefully would be able to use many of the apps that I already am using on my N800. In fact, I will now be able to carry my maemo apps around with me everywhere (the N800 is sometimes too bulky for me to carry all the time). Having a phone with the functionality of the tablet could also reduce complexity by reducing the duplication produced by using a separate tablet and a phone.

I don't expect my n800 to gather dust--it's still tremendously useful to me now. I'm hoping it will be my mini-device for places where cell phones are non grata, like planes and such. The larger screen of the n800 will be better for watching movies and playing games, etc.
