The machine is cheap, but the 'pods' (for want of a better term) are expensive, and they have to be ordered in advance for fear of disappointment in Tescos. If there is anything to be avoided in Tescos, it's disappointment, since our reaction is always, 'look it must be here somewhere' or 'they must have moved it', and so on. I have even found myself staring at the shelves almost believing 150ml of Ketjap Manis will suddenly appear like magic! Such bewilderment only encourages worry and we worry enough already.
Hence I am beginning to appreciate the genius in the Tassimo, having first encountered such a machine in a cottage in the wilds of West Cork, where it's owner no doubt also enjoyed such technocracy in retreat. He'd made, with his Tassimo, his cottage in to a space craft with none of the disadvantages of outer space, and enjoyed all the power of using it no doubt, making sure never to run out of pods, and enjoying the utopian pleasure in pressing buttons for sensual reward by himself whilst sitting in arcadia.
That's all very Archigram if you ask me.
