Wintel has tried to upsell notebooks to kill netbooks and promote growth in sales of notebooks but it’s not working. Ultrabooks are doomed to take only a tiny sliver of market-share because they are small but not nearly cheap enough in price. The real growth is in small cheap computers and neither Intel nor M$ are having much fun there.
Soon, OEMs will realize the way to sell more notebooks and to increase margins on notebooks is to ship GNU/Linux, cutting out M$. They can increase margins further cutting out Intel with ARM. The netbook was a great idea but the OEMs stopped too soon, at 10 inches. There’s no reason the technology could not support larger, more practical notebooks at reasonable and attractive prices. The market knows what it wants and it’s not more expensive notebooks.
