If you're going somewhere where there wont be plug sockets for a week (and I can only think of camping/mountain walking as an example) then you probably don't want to be contacted anyway!
Viewranger is useful during mountain walking trips, and having a large battery means that a person do not have to worry about changing batteries half way. Having a mobile is also useful during emergencies.
This does not mean that one should stop carrying paper maps and learn how to use a compass properly.
It looks similar, has lower capacity but a lot cheaper. I might get one for outdoor trips.
And then find out why it was a lot cheaper - it probably won't last particularly long.
There's been a lot of issues with the 3rd party/extended batteries - for Nokia and HTC devices at least, in that they just don't last long - the batteries just plain die on you.
Yes, this would be intersting. Please make some shots next to next in different angles, too.
Especially the stylus-side, which seems to add 2mm more to the thickness of the phone.
Are there any informations about recharging-times ?
in fact there are a lot of new postings, please don't forget to add some other pics which compare the N97 before and after mounting the battery-extension.
