Good feedback of DevCon in France, as stated in "Le Monde Informatique" (big reference for large companies) use your Goofriend translator if you're not reading Moli�re
Most feedback I've seen regarding DevCon was that it was a disaster. eg. bits.blogs.nytimes.com/2011/10/18/caught-between-two-conferences/
"RIM�s show for app developers for the BlackBerry and PlayBook couldn�t have been more different: noiseless and almost depressing, like a group of children who had been left at the mall by their parents, discussing how to get home."
