Be afraid

Oh God. We love technology, really we do, but it is a deeply depressing hobby at times. Just when you've spent a lot of money on one thing, the shiny next big thing is announced.

Take HD TV. For several years now the TV companies have been pushing us to upgrade our sets to the new HD standard. Not only will you be able to see every wrinkle on your favourite newscaster's face, they tell us, but it's a standard - unlike old TV, it's the same around the world, with no PAL vs NSTC, no wide-screen versus regular... one TV to rule them all.

Except it's not. Because some brainiac at Korea's Samsung has decided we all need to buck up and move on - to 'Ultra Definition' HD.

'Ultra Definition' apparently means 3,840 x 2,160 pixels - four times the 1920 x 1080 used by the current top-level HD standard.

To put this in perspective, film-makers are currently just beginning to digitally film movies in '4K' - that's 4096x2160 - so this TV isn't quite keeping up with that. But still, we just find it all totally depressing. Can't we all just agree to stay in one place, resolution-wise, for a while?
