Aside from the Kindle DX, there are only a few companies that make E-ink ebook readers with 9.7" screens, among them Onyx-International and PocketBook. Among the dozens of formats that the Onyx Boox M90 support are PDFs and CHMs. As a software engineer, I use it to mainly hold some reference books. As a comic book fan, I use it to read cbr and cbz files. The screen size is sufficient for reading all Worx and O'Reilly books. It's got a pretty big fan base in Europe and Asia, but not so much in the US. I actually heard about this device from an attorney friend who uses it to hold notes, exhibits, and opening statements. The Onyx-International M90 reader is the only one that is Linux-based (The GUI is QT). The company has a downloadable SDK that you can use to develop application. I heard that there's some games available for download online for it, but I've only played Sudoku on it.
Aside from my experience, you should take a look at some online forums like MobileRead and see what others have to say about their experiences with the devices. Also, the M90 can be found almost anywhere, Amazon, eBay, and on their website at onyxboox.com.
