Not I... and this evening my long-suffering Key2 appears finally to have given up the ghost: the keyboard has died!! I've just ordered a Unihertz Titan Slim from Unihertz's own online shop - I do hope they are reliable (does anybody know??).
My Pro1X (I was a backer) is now just a source of conceptual comedy, though naturally I am quite a large sum of money out of pocket. If I ever see it (which seems vanishingly unlikely) I'll be putting it straight onto E-bay or the like, as it would be a complete irrelevance... But I'm sure that is an entirely hypothetical scenario!
