When it comes to insight and analysis of the mobile industry, one of the essential people to pay attention to is Tomi Ahonen.
And his 10th (!) book on the mobile industry is not only forthcoming in print and mobile formats, but he’s also made it available as a free PDF download. I’m currently reading through it (It runs to 340 pages, with another 100 pages of excerpts from his previous books), and it’s a typically good read, in addition to being packed with valuable information.
It’s hard to imagine anyone involved in mobile in any capacity not getting a huge amount out of the book.
(While you’re on Lulu and freeloading, I’ve also spotted My Tiny Life by Julian Dibbell is also a free download, and is well worth a Christmas read if you’re interested in online communities and some of the issues and intrigue that can come from them)
