I am just back from the CompTIA member conference in Johannesburg, and a good event it was too. As always on these monster flights, I read books, magazines, papers, anything I can learn something new. I believe technology will become the next utility, to the point where you can’t see it and this is a great step in that direction. Light Touch, developed in Cambridge, can turn any flat surface into a 10-inch touchscreen. As this evolves, has connectivity and is integrated into portable devices, will it be goodbye monitor, keyboard and laptop bag forever? I hope so.
