I don't have an e-reading device, such as an e-reader or a tablet. Are they ebooks?

Of course! Ebooks can be read on a number of devices, including:

• A computer (PC or Mac)
• An e-reader (e.g., Sony Reader, Kobo)
• A touch tablet (e.g., iPad, Samsung Galaxy Tab)
• A smart phone.

On the other hand, it's much more pleasant to read ebooks on a device with a screen dedicated to reading, such as an e-reader or a tablet.
