Above poster is correct. The Passport 2004 actually classifies it as a
"portatop" because it combines aspects and convenience of a portable,
but also has features along with size of a tabletop. The thing is
known to eat batteries. Maybe you can use rechargables, but I don't
know if rechargable D's are that common. I think Radio Shack has them.

Compact? Have you actually seen this thing? Most tabletop rigs are far
smaller. Big is good as far as I'm concerned but I thought you might want to
know as some like small.
