Yeah! Ebooks is the solution to my problem of how to bring enough reading material with me on vacation without taking up all my luggage space. I will still take a few paperbacks but also plan to use the online sites to download books when needed. I downloaded the print version of Princess of Mars off Project Guttenberg, also downloaded a print version of Urban Legends from Googlebooks. Checked out Manybooks but don't have a pda so didn't download anything. I'll follow up on how practical this is while on an international flight.
