I'm not saying your wrong and i'm right...or the other way round. Just stating my opinion... and at the start it would be marketing, i see about 1 ad for another tablet once a month, but i see ipad ads all the time.
Also the fact that Apple has had a chance to see what works well on other devices and what didn't work would help them.
btw i'm NOT putting down the ipad, i'm going to buy one when there is stock in a city near me so i don't have to get on a plane for 3hours to some where to get one..also i like the app store :)
In my OP i was talking more about the original Ipods that apple made more then the ipad... when you saw it you new instantly what it was(thats the case with the ipad aswell..). If the other tablets makers advertised as much as apple you would see more of them.
Not going to reply if you do. i'm not disagreeing just posting my opinions.
