the famous apple / microsoft fight

It's been fourty years that the two big compagny are fighting on the device market. They are both international and develop in many countrys. I mean, it's huge. Apple cost like more than thousands billions of dollars. Everyone in the whole world know how to trun on an iphone or somthing... I remember when i was twelve, many of my friends already had phones and ipods. And it's became only commmercial. They publish a new phone every morning, like "hello, the phone that you buy last month is obsolet, please by the new one which cost 10% more". The newest cost more than 1000 euros. We are addict to devices ....
