I’ve been thinking that an eBook reader would be handy since I travel a lot.  I’m not really all that worried about taking novels and pleasure reading as much as taking along work related books and reference material.

I haven’t really done a lot of research into the various options (Sony, Kindle, Nook, iPad, etc.) but am aware that not all content can be read on all readers even if it is in ePub format due to DRM.

Anybody got a recommendation on which device/store combination offers the best selection of technical reference for a .Net developer with a particular interest in software process engineering?

HELP!!
