I say two-thousand ten, not two-thousand and ten. That's because it is not two numbers. 20-10 is not a year.
I know, kind of like how we said that the year was "one thousand nine hundred and ninety nine", and we never said "nineteen ninety nine". And lets not forget Orwell's classic "one thousand nine hundred and eighty four". I mean "Nineteen Eighty Four" sounds silly, doesn't it?
The last decade, we started using the full number because there was no proper way to say the 2 separate number system. It was unfortunate, but now we can go back to the better, shorter, more expedient system, and the system that sounds far more futuristic to boot.
I occasionally slip back into the longer system, but I make an effort to correct myself and say, "Twenty ten", because it sounds so much better.
