Now, the main issue is whether 2 batteries on this are impt.
If you are home or somewhere with ac, you are set.
If not, you get about 4 hours (??) with fully charged
If you have to use spare, you have to charge the battery in the zaurus as well, meaning powering down, opening back, switching batteries and rebooting. True? Do most sl-5600 users have spares , is it worth $80?
