Hi, in late august my dad bought me a toshiba laptop with centrino 1.5ghz. i get about 4 hours battery life while using wifi, aim, ms office, a few internet explorers, and listening to online radio. Now that the new ibooks have come out and i got a job im thinking of buying one and giving my dad the toshiba. i would like to know if i buy the ibook would it be slower then the toshiba. i would also like to know how much battery life i could expect out of the new 12in. mine is a 15 in and its not bad carrying it around, its just a little annoying in my lecture classes. i would also like to know if airport extreme thats built into the ibook will get the same reception as my toshiba cause i leech wifi from neighbor. Thank You very much for feedback.
