For me seems to be. I keep it in my front shirt pocket, pull it out to read all the time. I've gone through 8 books on it so far this year. That's 7 more books than I read on my Kobo by this time last year given how convenient it is to take it everywhere. Granted I'm usually a paper book reader so my Kobo was always just a travel device, but the Xteink makes it so easy to squeeze reading in everywhere.
