Why not just start reading? See what you think of it. And you don't have to read the book at your desk; pages are optimised for desktop computers, laptops, tablets and will scale all the way down to iPhone and other smartphones and devices.
Whether you're a purist and prefer books bound in paper or technologically savvy and like them electronic. This is where you need to go to find out what formats are currently supported.
