I actually think about this a lot. I bought a 15 inch MacBook and to me that's a lot of money. No laptop should ever cost this amounts. But it's so useful and portable. For me people need mobile workstations and then their media device that's not a phone. It used to be an iPod or psp/gameboy but now as we grow we want a tablet that can do what laptops can. And tablets are just an intermediate phase. They will soon die out once any laptop can have the screen detach Yet remain light, have a USB and micro SD and even have its own ten hour battery life. Were not far from it and I don't want to buy anything just yet
I don't know if tablets will die out or not.
Tablets were a forgotten thing until Apple released the iPad in 2010. Then they suddenly became hot. But the iPad is the only really successful product in the genre; all the other ones are wannabes. At least some of these other tablets have to prove successful before we can call "tablets" a market segment. Right now, there's iPad, a product from Apple. I am waiting until the offerings from other companies, running Windows and Android gain some market share so the segment is well established.
