Yes. Most devices support PDF, but a PDF formated for 8.5x11 paper shrinked down to a 5 inch screen makes it unreadable.
Most devices support some type of text format such as .txt, .html, .rtf. So, any books you can get in, or convert to that format will work with most/all devices.
Most devices support a "single" DRM (copy protect) format. Each device of course a different one. CyBook supports Mobipocket, Sony supports BBeB which is propritary to Sony's connect store, Kindle supports Kindle books (although I hear there are hacks to get it to support MobiPocket DRM since it's native format is basically Mobi.), iRex Iliad... not sure what it supports for DRM format.
Those are the big four for eInk... There is also the Hanlin V3 but that doesn't seem as popular.
There is also the eBookWise which is an LCD device.
Of course, most PDAs run the Palm Reader or is it eReader format.
That is why, if you really want something for PDF's for the most part... a tablet or UMPC is the best bet. Bigger screen, basically, plus it will run Adobe Reader, eReader, Mobireader... but then again, battery life is much sorter and weight is much higher.
