On the battery issue.. The battery used by my phone, the k750i from Sony Ericsson, is a Li-PON (I thought i read somewhere that it stands for lithium-ion polymers). I never heard of this type anywhere else, but it's great. Stand-by time: 400 hours and it's fully charged in about 1 hour or so. The phone's camera also poses no problem for the battery. I mean, it's not that after ten photo's the battery is dead. Anyway, i wonder why it's not more widely used, for example in this new unit?
