Intel’s Ultrabook mobile form factor requires very specific components which is causing a great deal of concern among component makers.  The parts that are designed specifically for Ultrabooks are not necessarily useful in any other form factor which makes them unattractive to manufacture since poor Ultrabook sales would mean that they are stuck with a large amount of unusable inventory.  If that concern limits the supply of parts for Ultrabooks then we could see a self-fulfilling prophecy as poor availability at the retail level will lessen the attraction for both consumers as well as major laptop vendors who may not want to include a product that might or might not be available for a customer to purchase.  DigiTimes points out that because of the previous failure of Intel’s CULV form factor, many of the manufactures are already leery of the Ultrabook.  We shall see what effect that has on Intel’s sales over the next few months as Ivy Bridge hits the market.

"Component makers, seeing their downstream brand partners are aggressively entering the ultrabook market, are concerned that if demand for ultrabook is not as good as expected, their inventories could hurt their performance as ultrabook components are mostly custom made and cannot be used in traditional notebooks, according to sources from the upstream supply chain."
