Stephen Fry is a man on a gadget mission.
Here's a very subjective question: What is the most important gadget you have?
A gadget you would otherwise struggle without, or panic if one day you discovered you had mislaid the thing.
But before we embark on that course, let's just clarify exactly what a "gadget" is.
According to the dictionary I have here (which is a remarkable literary gadget I could not do without) a gadget is a small mechanical device or tool, especially an ingenious or novel one.
You could, I suppose, also call a gadget an appliance, apparatus, instrument, implement, tool, utensil, contrivance, contraption, machine, mechanism, device, labour-saving device, convenience, invention or quite simply, a thing. Some people call them gizmos.
Now while it is not novel, or particularly ingenious, I daresay the humble can or bottle opener steps up to the mark pretty well.
As does, I daresay, the remote control for the telly.
I was one of the first people in the country to have a remote control unit ... even before they were invented.
It was a 3m-long length of solid dowling which I would wield like a sword - leaning forward and tapping either the "one" or the 'two' button on the telly.
It worked a treat, but I was conscious of the fact that if I had tried to market the concept it would have been a financial disaster.
Now one chap who is very passionate about gadgets, and the more bizarre and intriguing the better, is man of words and humour Stephen Fry.
The QI host also fronted a show centred around the most valuable and important invention known to humankind ... and I think he came up with the lighter.
I suppose we all need to ignite something at some time, but I always figured the spoon was top of the tree. Try eating soup with a knife.
Like one's favourite gadget, the most important and valuable invention is subjective.
So, ready to spark debate and conversation, Fry has embarked on a series detailing gadgets. All sorts of gadgets from the bizarre to the practical.
The time-saving gadgets and the highly technical devices. And the games and the tools and the ... slightly out of left field.
Such as remote-controlled pets, an automatic cocktail maker and a pool table programmed to line up the shots for you.
But like all good critics of devices large and small, practical or pointless, Stephen brings in some chums to cast their eyes over the gadgetry landscape and they too deliver some interesting angles.
Along the way in his dalliances with gadgets he called on the likes of Jonathan Ross and Jo Brand, so expect some entertaining opinions.
In terms of imaginative gadgets, one of the most remarkable I have come across is a 3D set of headgear-mounted glasses which are being used as part of the Air New Zealand history show down at Te Papa. They put those who donned them into a glowing 3D world ... one minute on a tropical beach watching scuttling crabs and next minute a moa comes dashing by. Now that's what I call gadgetry. So would Stephen, because as well as his gadget-seeking journey he too touches on a 3D headset.
Bottom line, at the end of the day, to cut to the chase, in the long run ... Mr Fry simply adores gadgets so, yes, he's the best man for this Sunday night mission. Oh, and you'll need your remote control to find him.
Stephen Fry - Gadget Man, Prime at 6.30pm Sunday:
Being a more versatile and learned man of words than I could ever be, Stephen, I daresay, will come up with more colourful descriptions of the gadgets and gizmos he rolls out during this new series. Some will astound while others will make you wonder why anyone bothered to create and market such things ... and who indeed supports such business ventures by buying them.
