I only try the mobipocket reader for .prc files..

Is .rgo better?? :noidea: :noidea:

it's a matter of preference what kind of handheld device are you using anyway? Im using ipaq 3900 series rgo is my preferred ebook format. but my sister prefers lit so we have a different opinions of what kind of format we use to read. so there is no such thing as which is better otherwise it will become an endless debate.
