It’s like living inside a technical support certification exam.

Everything in life can be explained with three circles. Except bicycles.

As I tweeted on a frosty Christmas afternoon, Santa tucked an iPod Touch into my stocking. I had explained earlier to Carole -- Santa's agent -- that I "needed" one for a) a mobile app project that I start in the new year, b) translation for our upcoming Korea & Japan trip, and c) because it's totally cool and doesn't require a soul-crushing contract with Bell Immobility.

So now, what with Carole buying a reconditioned MacBook Pro from her school, our house literally hums with operating systems:

• iOS,
• Mac OS X,
• Android,
• virtualized Windows XP/Vista/7,
• two flavours of Ubuntu Linux, and
• whatever it is that's running the kettle.

All we need now is a Blackberry and the thing that Palm is grasping as an emergency flotation device and the circle will be complete. Heaven help us when it comes time to upgrade.
