I got the X4 just before my summer holiday and put "War and Peace" from Project Gutenberg on it as my only ebook.

Five weeks later, I'd finished it, all 360 chapters, 1400 pages.

Apart from finding War and Peace a totally engrossing read, one of my favourite books of all time, I give the credit to the X4... I'd never have finished it if reading the physical book (too large to carry around) nor if reading on my phone (too many distractions).

So thank you xteink!
