The smartphone, pc, laptop, netbook markets are all mature and saturated so the only way they could sell a new product is to invent a new market.
Its pretty wasteful, you have a device that can't replace any others so you have one more device to buy every few years, keep charged, etc. My netbook replaced a laptop so it was a good buy, my laptop replaced a desktop so it was a good deal too. With this its just another mouth to feed.
I'm not saying your wrong. What you say makes a lot of sense.
I really don't have a dog in the fight. I'm not a heavy tech/media/messaging user. As of a couple years ago I didn't have a cell phone and still use a cell phone only as a phone. I have never even sent a IM and check the e-mail once a month or so. I have friends that seemingly IM every thirty seconds, are always on the phone, and are never more than a foot or two away from some sort of computer/messaging/media input.
But a whole lot of people love, desire, the benefits of computers but want to avoid interacting with the PC.
