GPS/WiFi

When buying a portable device with gps and wifi, are there different levels of quality or is a gps always the same, no diffrent from any other device? I mean, is there some wifi that can read stuff like java and other that can't?

There shouldn't be any noticable difference.

is there some wifi that can read stuff like java and other that can't?
I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

basically, not understanding wtf wifi is, just wanting to be able to have a portable browser.

People who can't be bothered to even casually look in to how ubiquitous technology works shouldn't be allowed to use it.

I guess that's why your mom wasn't allowed to use a condom...

Protip: condoms go on men, not women.
The female condom has only been available for a decade and a half.

SO'S YOUR MOM DUDE

gps or gprs?

as in cellular wireless networks?

as in, sprint's network vs. ev-do vs. cingular's 3g vs. edge(horrible)

all vs. wifi?

as in, you're buying an iPhone and you're confused that it uses both edge and wifi?

tell me if i guessed right please :D
