Given:
An Airport Extreme (a)
A Drobo (d)
A MacBook(m)


Prove that:
a + d + m = 2 GB of wireless "Airdisk" backups for all values of m where m === Leopard

In English, the Airport Extreme 7.3.1 firmware now allows you to connect to Airdisks (like my Drobo) connected to an Aiprort Extreme via Time Machine!

OK, in less technical jargon, for those uninitiated with the latest Apple innovation, what this means is that I can buy some hard drives, stick them in a hardware chassis which provides hassle-free storage of up to 2 Terabytes of storage, and to use that storage wirelessly to back up all of my Mac laptops without having to lift a finger or without having to plug in a USB cable into my laptop.

So, say I pour a soda on my laptop and lose all my data. So long as I've left my laptop on for a few minutes in the previous 24 hours, my Mac will have simply and without my intervention, backed itself up to a practically unlimited, redundant wireless storage/backup solution, and at most I will have lost < 24 hours of data.
