How do you move around? For a car, most lighter-to-usb chargers will work fine. And it also lets you charge the phone on the way to/from work/shopping, so you start out with a fully charged phone. Such a charger can be made to work on a motorbike too. For bicycle, consider one of these: * DIY connection to a bicycle generator. * Bring extra phone batteries * Bring a small 12V battery and the above mentioned usb charger. That battery can be much smaller than a car or motorcycle battery. > The development is getting big steps quickly, I've read Paroli is now > working, the first killer apps are on the road, but I think we need a > decent WiFi support and a less hungry kernel... how near are we? The kernel will always be hungry when you do gps logging, because the processor must stay on in order to move coordinates from the gps chip onto a file - once per second. (tangogps will need more power because it also draws a track (can be turned off) and your position on the map. "cgpxlogger" can be used to just log to a file without displaying anything, maybe drawing slightly less power. Don't know if it is ported to arm though. I find tangogps more useful for openstreetmap, because it shows me what is in the map already.
