Probably not. But they kept saying that about the iPods... and how the next MP3 player from XYZ company was the next iPod killer... never happened. Even Microsoft's Zune couldn't unseat it. Finally what brought down the sales of the iPod was the iPhone and other smartphones unifying cell phones and music players in one device.
The thing is that it's not just a DEVICE that has to compete, it's a device plus the ecoSYSTEM that goes with it... the stuff that ties in with it. Apps, accessories, devices that transparently work with the tablet without jumping through hoops to get them to work. That is what make the iPhone, iPod touch, and iPad ecoSYSTEM harder to compete with another phone/player/tablet. So many things are already iOS compatible and not compatible with the competition.
That is where Android is going as well.
I would love it if the tablets could eventually replace textbooks and paper.
It seems like yesterday that the Apple naysayers were laughing at the name iPad, saying it sounds like a sanitary napkin. They said there was no market for a product that is between a smartphone and a laptop but is neither. As usual Apple proved them wrong by reawakening a dead concept by improving it and making it attractive, fun, and full of unrealized uses.
They aren’t through, either.
