Are any of you guys using ebooks? I'm considering switching over to ebooks rather than buying physical books once the Samsung Galaxy Tab is released locally. I know there are ebook readers out there now but I prefer to get a multi-use device.
My main question is am I being held hostage by the hardware/software with regards to the ebook formats? What format does ebook stores like Amazon and Barnes & Noble use? I've got an android app that reads the .epub format.
