My 8746 DFM GPO telephone, that I have had since 1968, doesn't have touch tone technology. Press, or in my case, dial, one for the money, two for the show and you cut yourself off. We had to install a modern phone alongside it, not so much for the tech compatibility, as for being able to see the incoming call's number. If ever there was a case of rant inducing technology it has to be The Bosch cooking hob. Our former, rather cheap, electric hob shattered, my missus wants a Bosch. It cost a ransom, but it keeps life sweet, she has her Bosch. I forgot to add, that it's electric, not gas. There are no dials, to make adjustments in temperature you have touch pads. In order for them to work you must ensure that they are perfectly dry, in a cooking area, your finger is perfectly dry and you have limitless patience. You can stand there for ages trying to get the thing to work, just remember to start cooking about ten minutes before you used to. Wretched thing!
