my blokia gets 3-4 days on a charge, it is my ipod, it is ringing all day, but wifi does drink battery charge, no worrys i got a spare battery on me at all times
as for tablets... their a gimmick, like laptops, i understand the purpose... but most folk who need a laptop on the go i know use pda's/phone/ paper + pen
onobdy ever moves their laptop, so the tablet will be near the same
