I'm looking to buy a Dell Streak in the UK (anyone got one for sale?!) to used as an in-car satnav using either CoPilot Live or Sygic. Does anyone have any experience of using the Streak in this fashion or would I just be better off going for a Tomtom / Garmin instead? I'm a bit worried that it wont be bright enough or may be unreliable with GPS locking etc. Any comments would be greatly appreciated!
