How can lead from behind when none of those products is selling really well. They're not trying to catch race horse there, they're simply waiting for the right moment, right tech, right experience to enter the market with a good product. I suppose the Iphone was also "leading from behind", guess they should continue failing in that exact same way since it gave them 40B in profits a year.
So, if Apple comes out with a Ipad PRO and sells 5-10M of them,they'd suck because they are not the first even they are the first successful at it ?
I suggest you reread what I wrote. As well, Apple iPad sales compared to other makers, is not doing that well (though iPad holds a large part of that market due to return buyers). Apple starts ahead of the gang, others catch up and often surpass in features then Apple releases a newer model. The question remains whether the newer model is better than the other makers offerings. This is strictly in reference to technology and features. Apple hasn't offered any great improvements for a long while and thus is leading from behind on technology. Last year, iPad sales dropped, meanwhile items like chromebooks increased 160 percent. The point remains that Apple does what Apple wants on Apple's own time, their market model and depend heavily on promotion and NOT real innovation during certain periods of sales and development.
