Hey there,
Good to post for the first time. I know I found some 1100mAh
batteries for $12.50. What I did was buy three of them and
keep them in my travel case. I have a travel WIFI router that is
about as long as a credit card. I also have a compact flash
camera and 56K modem in case I have to dial to get internet.
I also picked up a thumb keyboard that slides onto the bottom
of the X50 for quick typing. All these items fit in a case about
the size of small novel case. I usually hook this onto my belt
when I travel. It's like having an electronic swiss army
knife

. This also means I do not have to worry about the
carry on issue with planes. I can still take my backpack as
well. Right now I am looking at a solar panel backpack so I
never have to worry about my devices going dead. Yes, they do
make them. Well enough of my spill

. Take care.
