Can you remember back to the early sixties to when computers first came onto the scene? Back then IBM ran a full page advertisement plugging their latest models - that for just £25,000.00 your company could enjoy the full use of this high tech wizardry to sort out your Sage and other money matters at the touch of a button. It filled a third of a room, and was selling like hot cakes.
Of course new techknowledgy is expensive when it first comes onto the market Look at the cost of the early camcorders when they first came onto the scene. Very bulky and all mechanical. Back in the early seventies a woman came into an evening course which my late father and I was attending and announced that if she could get everybody to pay £20.00 up front, she could get these Sinclair Cambridge calculators in kit form at a massive discount. My father turned down the offer, telling everybody that once they came down to less than a fiver, he would think about getting one. There were hoots or derision from the entire class, and we were immediately "sent to Coventry". We had the last laugh - that was the last anybody saw of their calculators or the woman 
My father had to really bite his tongue not to return the ridicule - now they give them away. Get what I mean?
Technical advancements are happening all the time. Those Braille machines will be available for well under £100.00 once they start mass producing them. You once needed to add a modem to your computer.
Our technical achievements are limited only by our own lack of imagination. If God spares me, within ten years, if the need arose, having Braille on a home computer at the touch of a button would be available - the there was a big enough demand for it.
And what's 1.2 million pounds - pin money when you think of the potential returns!
