Can't succeed by copying others?
Have you ever studied the success of Japanese companies in many areas?
The have taken over entire industries.
And that started via copying, which is like learning what works, add some ideas along the way and bingo ..success!
Yes you are right, they see something, copy it to begin with for a lower price and then make it better.
Giving the customers extras for free/built in that they had to pay for on the original model.
They then increase it's power/quality/speed and often the original maker is just too stuck in their ways and too slow to respond, or just pig headed so won't change.
Apple are up against the big boys now and they don't like it.
The only way they will be able to compete is by genuinely making their devices better constantly.
It's like any race, just because they have started before the others and have a 1 lap lead, the others are now off the starting blocks, and if Apple does not keep on running, the other group WILL overtake them.
And no amount of moaning and lawsuits will change this in the long run.
Apple have their nice little niche with the iMacs and Macbooks where they do what they like and they don't really have to worry to much about PC's taking their loyal customers.
On the Tablet front, it's very early days and there are still hundreds of millions of fresh customers out there to get onboard your system.
More and more of them buying Android/Google phones every day.
Apple has to concentrate on excellent products that don't handicap the users, and promote a company image that people like.
If they gain a negative image, and boy, they seem to have been doing nothing but trying to create a negative image over the past year or so, well, we'll see long term I guess.
