Dear list, This is Joseph. I would like to comment on this (actually a suggestion). A lot of devices these days use Lithium Polymer batteries (those used on PAC Mates). I have a quesiton for HW staff: are there any future plans to switch from Lithium Ion to Lithium Plymer batteries?

However, a higher-capacity battery would take development, too (I assume). As I have said before, I heard about a battery that plugs into the power socket of the BN in a 2004 conference on the HW site. It seems that the better battery could be developed to plug in, so that people would not need to send in their units just to have the battery replaced with the new one. Because the battery is currently built in, a user has to send their unit into HW and wait a few weeks to get it back, just because of normal ware and tear. That is a major reason for my opinion on the removable batteries. The slot into which that battery would go could be on the corner of the unit, so there would be minimal chance of a wrong battery being used, or of the correct battery being forced in wrong and damaging the unit. Just some thoughts.
