You have nothing to lose but your cubicles and your sense of day-to-day security: Companies are starting to look big-time into allowing flexible work environment that don't lock people into a single cubicle or office. This allows them to use office space more densely but flexibly and lets people work more to their liking. Of course, some people like a cubicle, don't they?
One of the drivers for increased mobility is that thin APs require less management--a claim long made by thin AP makers and confirmed when Cisco bought Airespace--and greater flexibility. It's clear Microsoft chose Aruba not just because they were thin, but because their approach is commodity-driven with enterprise-class management: that is, magic in the APs is less important than magic in the central console. (Microsoft may also have chosen Aruba because of its remote AP option in which APs can be added using IPsec security over any remote Internet network.)
The other drive is, of course, 802.11i and its integration into branded standards as WPA2. With WPA2 Enterprise, companies finally feel like they have the strongest possible security at their disposal.
