I sit on the top deck for forty minutes as it slowly migrates towards Victoria, then hop off and head for an all-you-can-eat Chinese buffet for lunch. It's stowed out, as you can imagine, because I've hit peak lunch time; but it makes a welcome change from the dismal little pie shop round the corner from the New Annexe. I emerge into daylight with a full stomach and my sense of well-being marginally restored. It's trying to rain, lonely drips spattering the pavement and evaporating before they can join up. I shuffle along with the tourists and foreign language students and shirking office workers, staring into shop windows and feeling faintly wistful, something nagging at the back of my mind.

The penny drops. My PDA! Okay, it's Laundry-issue. But it's toast! Sure I have a cheap, dumb mobile phone as well, but I relied on that PDA; it had my life embedded in its contacts and calendar. Yes, there's a backup, but it's on my office PC, which is most definitely not a laptop and most definitely not allowed to go home with me—the last thing the Laundry needs is headlines like CIVIL SERVANT LOSES LAPTOP: ENTIRE POPULATION OF TOWER HAMLETS EATEN BY GIBBERING HORRORS

FROM BEYOND SPACETIME—so for the time being, I'm adrift. If Mo called me right now I genuinely couldn't phone Pete and Sandy. Help, it's a crisis! Well okay, it's a minor crisis, but I rationalize: obsessing over my lost address book is a lot healthier than obsessing over a blinding purple flash and an imploding face—

Besides, shopping is therapeutic. Right?

I pull out my phone and look at it in distaste. It's a cheap Motorola jobbie with a pay-as-you-go SIM, and its major virtues are that it's small and it makes phone calls. I bought it a year and a half ago when word went round that IT Services were threatening to inflict Arseberries on us along with a centralized work directory, and start billing for personal calls. The rumor turned out to be unfounded but I kept the phone (and the PDA I wangled Andy into signing off on) because between them they did a better job than the old Treo, and besides, all smartphones are shit these days. It's the one industry where progress is going backwards in high gear, because the yakking masses would rather use their phones as car navigation systems and cameras than actually make phone calls or read email.

About the only smartphone that doesn't stink like goose shit is the JesusPhone. But I've steadfastly refused to join the Cult of Jobs ever since I first saw the happy-clappy revival tent launch; it brought back painful memories of a junior management training course the late and unlamented Bridget sent me on a few years ago. Nothing can possibly be that good, even though the specifications look rather nice on paper, right?

You know how this is going to end . . .
