When I'm out and about I have David Weber's Honor Harrington series on my PDA as ebooks and I'm re-reading them in anticipation of the new one due next year. I just finished the 3rd one and am well into the 4th.
Honor Harrington on a PDA! Oh Yeah! Nearing then end (At All Costs) of a re-read, all on the PDA. Gotta love Baen Books!
