I love the con book and I'm considering hanging some of the artwork in my room now! Though I have to admit shamefully that I didn't give it a good cover-to-cover read through until after the convention (and I'm certainly not alone there). XD When I got it, I went straight for the schedule and the event descriptions.
The advertising didn't strike me as negative because it was thematically appropriate, actually had some nice looking artwork, and (most importantly!) didn't intrude on the content. An ad for "<insert popular soft drink brand here>" would have looked entirely out of place, but I don't think there is anything questionable about furry events promoting each other, or related events and services. (And I think the amount of advertising in general was rather low. On a quick look I'm counting 5 full pages, not counting the "end tide" page, and two banners on the bottom of other pages. That is less than 10%. Next time you go to the dentist, flick through some of the crap mags there.)
I also entirely missed the pocket program, but I sort-of invented my own version of it by printing the online PDF in "2 on 1" mode so it comes out in A5 format if I cut it in the middle. Then it fit nicely into my A5 note book that I was carrying around most of the time anyway, I can text-marker interesting events beforehand, and if i put the last page in upside-down i can just flick out the whole program to quickly see the floor plan. (Only slightly larger font and b/w printer friendly contrasts would have been nice for that, but it worked great nevertheless so no complaints.)
And last but not least... I LOVE MAPS!!!111 <3 And the online PDF was great to familiarize myself with the general layout before I arrived.
Oh, and I didn't use the "app" because I was the only person at the convention without a smartphone and unlimited data plan. Please keep the printed stuff as well, and it works without batteries.
