New Proxim AP

Proxim, our wireless vendor of choice, has released a new access point model today, the AP-700. I haven't nailed down what's new and different about this unit yet, but to me, it looks like an AP-4000, only with either 802.11b/g or 802.11a, but not both. Why I'd choose this, rather than the AP-600, is unclear right now, but hopefully I can get one to play with after my return from Russia.
