Hi folks, so I'm torn between using a 'smart phone' or an actual GPS unit such as the Garmin Edge Touring. As of now I have a little Tracfone that gets the job done. (Plays music, makes phone calls/texts etc.) But it doesn't have GPS. So i'm wondering if I should upgrade to a smartphone but i'm concerned with the battery life and the glare from the sun (plan on mounting to my handlebars).

Here are my options for smart phones. I'll be going with Virgin Mobile if I do get one. Can't complain for $35 a month.

-http://www.virginmobileusa.com/shop/cell-phones/lg-optimus-f3-phone/features/ $99.99. The features note that it has good battery life which is definitely a plus. But not waterproof so I'd have to buy a special case and mount.

Or

-http://www.virginmobileusa.com/shop/cell-phones/reef-phone/features/ $74.99. Only 3G but i'm not really to concerned with that, and it claims to be waterproof. However people are compaining about insufficient battery life. Will have to buy a mount too.

Or should I just get an actual GPS unit and stick with my tracfone? I don't really care about fast internet and whatnot with a smartphone since i'll be occupied with more important stuff on the road. The only downside is the Garmin Edge Touring is $250 which is pretty damn expensive, but if it lives up to the expectations it'll be worth it hopefully. Anyways, suggestions are much appreciated!
