When it comes to usage, it seems to me there are actually two kinds of computers. To break it down --- First there is the Primary Computer. The characteristics of it as follows: 1. Moderate to high cost 2. Mobility is moderate to stationary. 3. Large screens 4. Large local storage. 5. High processing power with high power consumption 6. Multiport, serves as a hub to other devices 7. Long usage cycle prior to replacement 8. Content production The Secondary Computer, on the other hand, has these characteristics. 1. Low to moderate cost 2. Moderate to high mobility 3. Moderate to smaller screens 4. Moderate to low storage 5. Limited ports 6. Low power consumption 7. Shorter usage cycles prior to replacement. 8. Content consumption. Desktops, gaming rigs, high cost notebooks, workstations would fit the category of the Primary. Smaller notebooks, netbooks, tablets, and even smartphones, would fit the second. For a long time, the Primary Computer has dominated, but in the last years starting around 2007, we saw the rise of the Secondary Computer, to the point that this is in fact, we see a lot more sales are being accounted for. The sheer cost, longevity of Primaries mean you are going to have lower turnover as demand is satisfied, and the demand for replacement is lower. On the other hand, high disposability and the lower price points means the Secondaries are going to inevitably dominate the market. But for a Secondary to actually succeed, it has to meet all given 8 criteria, and that hybrids between the two --- combining features of the two --- isn't going to work, despite the initial attraction of having to blend features by combining the advantages of both. The thing is, all 8 of the two sets are basic criteria are synergistic to each other, each a node that reinforces each other in a dependency circle. Breaking the circles with a hybrid isolates each characteristic, and the resulting product becomes less certain of its market intention, in essence, becomes a compromise.
