Folks, I need some advice. My standalone GPS, a Magellan Triton 400 has seemingly died and before I spend a few hundred bucks for a new unit I'm wondering if I could just rely on my Droid X with a Topo map app such as Locus or Backcounty Navigator.

Questions to me are:

Ruggedness
Battery Life
Screen Size
Ability to pre-load maps
Reception

I'm not usually a fan of multi-function devices but since I can also use the Droid for phone calls, messaging, first aid apps, etc. it might be a viable option.

What do you think?
