Glad to here that you got your Netbook. Asus makes some really nice machines.
When I knit out a machine, part of my original load up includes the following which are related to reading in some for or the other.
Mobipocket Reader (And Creater to make my own) for PRC
Adobe Reader or Digital Editions for PDF's and EPUB
yBook (Free From
Spacejock Software) to Read Html, Rtf, Txt and Pdb files. Its free and privides a very nice book like layout to read on.
CDisplay for reading comics and photo archives in CBZ (zip) and CBR (rar) files. I often create my own archives from Image files and find that using this is one of the easist ways to view them.
