When selecting a tablet for reading eBooks in various formats such as PDF, DJVU, MOBI, and EPUB, compatibility is crucial. The iPad supports many eBook formats, but it may not natively handle all of them without additional apps. Alternatives like Android tablets and dedicated eReaders may offer broader compatibility with these formats. Users should consider tablets that allow for easy installation of third-party applications to enhance format support. A comparison chart of eBook formats can provide further insights into compatibility and features.
