Well, I can still update the map on the device.

The SonyEricsson Xperia Active is not that bad. It might be the only 
outdoors-proof smartphone that supports ANT+Sport sensors. The GPS might 
be a little less accurate than the Edge 705, but I have yet to do an 
apples-to-apples comparison. (The reception will probably be much worse 
in a jacket pocket than on the bicycle handlebars.) I will install the 
SportyPal handlebar mount soon.

That is easily fixed by using a charger that connects to a bicycle 
dynamo hub. I have used such a setup for 3 years now, and never ran out 
of juice, even on multi-day trips.

No.
