Funny really, you're commenting that teachers don't know what's needed in the workplace whilst yourself not knowing what being a teacher is like.
Or to sum it up more accurately - what a pile of nonsense.
Tablets are not useless, they have some great uses in education. The problem comes when someone buys into the sales drone's bullshit and buys them before actually having a need. Tablets are great in music and SEN. They're great as a "companion" device - so, for use alongside traditional materials and methods. No need for planners, calculators, printing periodic tables, handing out homework, booking an ICT suite to allow your class to do some research on a topic, etc... The question is value for money - all those things can be done without tablets, but do tablets do it better, cheaper and more conveniently? I'd say that with recent cheaper X86 based tablets coming out that they absolutely do.
ICT as a subject has been a joke for over a decade. When I took it, it didn't tax me as a student a single time. That's why the government and industry are trying to reform it into something useful - which takes time.
Teachers have a difficult job, and people like you don't make it any easier.
