Extensive use of a keyboard will soak up battery power like mad. I nearly drained mine in two days when I was on an off site trip. <br><br>re: Sled. <br><br>Let me see if I have this straight...<br><br>Get a spare serial connector that fits into the Palm slot and wire it to 4 AA batteries (1.5v each = 6v total). Additionally, a solar charger could be used to (a) recharge the 4 AA batteries or (b) wire into the Palm serial connector to charge the lithium battery directly.<br><br>>>>If I had listened to my brother more closely years ago... I had no idea how truly useful it would be until I (almost reluctantly) got this one several months ago.<<<<br><br>BTW, I bought my wife a Handspring this Christmas. The first words out of her mouth when she unwrapped the gift were, "What are you??? Nuts??? Why would I want one of these?" Needless to say, she's a techno-phobe and I returned the PDA. :-) Oh well.
