I agree that AMD is chasing its own tail here. The netbook craze lasted about 3 years, now they are nowhere. The tablet phase too will pass. I don't mean they will stop selling them, but I don't think they will be the hottest item for long. Remember PDA's? You'll have too many "me too!" type products coming to market, then you'll have legitimate contenders with Apple. At any rate, when consumers can get the same experience from a phone the tablets will become somewhat passe.
With the netbooks, the lack of power and graphics holds them back from keeping a large market share. Noone wants to pay $300 for an inadequate laptop, we can see that now.
Obviously mobility is here to stay, but form factors will change. What I think AMD should work on is wireless connectivity, such as the wireless video tech in the core i3/i5 processors. Moving all devices toward wireless and mobile just makes sense for what consumers want.
Think about this, if all these devices connected wirelessly regardless of protocol (bluetooth, wifi, 4G, or some newer tech) because it was built into every APU people would certainly buy this. Let's say you enjoy the tablet because the larger touchscreen works with your big hands and is easier to write with. Depending on your location, it would use the fastest connection available to stay permanently connected except for the most remote rural areas. You can also communicate with any networks that use different protocols. You can walk into a meeting room in the office building of a competitor, wirelessly connector to their projector, and show them with your tablet why they should accept your proposal. Communication would no longer be limited by technology but actually enhanced by many times what we enjoy today. Phones are very close to reaching this ideal, but still have some limited internet usability. It looks like WIN8 will move toward this type of convergence. The way I see it, form factors will come and go but mobile connectivity and communications will continue to be at the center of everything. Hopefully, AMD will have some folks smart enough to figure this out before putting all their efforts into one form factor or another. Work on refining the APU to be a very powerful yet small and mobile processor that can power any number of devices. Then show the world that you have the facilities to keep up with demand for such ubiquitous devices.
