i'm getting a laptop and i'm not sure what the difference is between a/g and b/g wireless or if one is better then the other or if it even matters at all.
802.11G is 54MB @ 2.4 GHz Best range 802.11B is 11MB @ 2.4 GHz Cheapest 802.11A is 54MB @ 5.0 GHz best for built up areas, to avoid interference or if you are using a TV sender box.
