Tracphone isn't web browsing, it's pay per minute to go through their portal and it's restricted view. Get a test drive at a store or from another user willing to part with the minutes and you'll see it's slow, the screen size on the 500G restrictive (even if it is huge compared to most flips or bar phones,) and for me, the system won't access something as simple as weather radar without timing out - and still charging me minutes.
My oldest son got a 3G Iphone, at $75/mo it's still a luxury compared to the real use of even a small netbook for less than $30 a month for DSL. He pretty much restricts surfing to where wifi is up, to increase download times and get faster response. Another user at work only gets to use it on lunch break or in bad weather to check radar, most of the time he's simply too busy on the clock to sit around and get paid to surf. Battery life is poor under those conditions anyway, a daily recharge becomes necessary.
Take a longer look and see if it's really what you want - my youngest son is on a boostmobile $50 a month pay as you go plan, and even he doesn't use the web much on his phone. Plus, $50 is killing him to keep it up, he's finally realizing (at the wise age of 16,) that it's expensive. He's trying to move the phone to a cheaper plan with no Web without losing the use of his special phone.
