Deviant - I bought one of the Quechua phones this week
going up from my HTC, I'm very impressed so far
Warning, when you first take it out the box, its big!
However I'm finding that a blessing - much better for emails and bloody brilliant with map/gps, even OK for programmes and kindle - and its actually not a lot bigger than an iPhone or similar in a water resistant case
First day or so I was a bit worried about the battery life, not what I expected, then realised I had had GPS running all day - after installing the 2x battery life app which powers down things not in use, its currently reckoning that it will stay on standby for another 374 hours...
Voice is very clear
Its got some nice functions in the settings like a warning on monthly data use - since its unlocked I can get a cheap sim deal from any of the big companies
Only complaint so far is that the camera is not very good - however improved a lot after changing some of the settings, but still not brilliant.
overall, I'd say it's *almost* the perfect phone to have in your camelbak - if the camera was a little better it would take the title
