A great selling features of the Apple iPad is iBooks, the app and online store that turns the iPad into an eBook reader. You do NOT have to buy eBooks from Apple’s iStore to read eBooks on the iPad. Other eBook formats are supported by the Apple iPad. The follow is a great list:
ePub – is an open ebook format that is used by many online stores. You can also convert other formats to ePub and then sync them to the iPad via iTunes.
PDF - (Portable Document Format) is the reigning downloading document format on the website, so you’re likely to find ebooks in this format. The iPad lets you load PDFs onto your iPad and read them via third-party apps.
iBooks – the books purchased through the iBooks Store are actually in ePub format, but include DRM to prevent unauthorized sharing or copying.
Kindle - Amazon’s Kindle isn’t just an ereader that competes with the iPad, it’s also an ebook format. Though you can’t read Kindle books through the iBooks apps, you can read them on the iPad using Amazon’s Kindle app.
Barnes & Noble – Just like with Amazon, Barnes & Noble has an app that lets you buy read books purchased from their online store on the iPad.
