I'm thinking the Christmas break didn't help your device count :)
Looking at Aruba's numbers over the last year we've seen probably a 60% increase of devices in the corporate network. Some of that is hiring, but it's not 1-1. Practically everyone at work is now carrying two devices, I show up with 3-4 devices every day. Count in wireless printers, game consoles, digital picture frames, etc. and you're going to get a ton of new devices. Our planning guides are recommending at every user now count for at least two devices.
