The race to the bottom as complained about by tech reviewers (get the product for free), is the quality and value of the high end is reduced because the market is smaller due to people choosing a cheap option. With less competition and economy of scale in the high end there are less options with lower value.
Hypothetically if the cheep options were removed from market and you could only buy laptops that meet the ultabook spec, you would see a lot more diversity and value of Ultabooks.
Mercedes, BMW, Smeg fridges or Learjet aircraft.
These are strong brands like Apple that have universal brand recognition, OEMs don't really have this. Yes, some are more reliable than others but to the general public its still a windows laptop.
Just in case it did not come through, I think the race to the bottom is a good thing for the average consumer and me personally.
