I think the organization is good. However, the Conference and Sessions guides are way too big, and you are bothered by getting them in and out of your backpack. It would have been better as in previous years, as a small booklet that would fir into your badge pouch, so you could make it to it really quick.
I did not try the app.... I have a blackberry device, and therefore no app. Also the susbscribing to the calendar online was really bad... No details on the speaker (Not even the name). I attend TechEd because of the speakers, and this year many of the big SQL Server Non-MS Rockstars are missing.
