Sources from tablet PC makers said that the component shortage is preventing their shipment volumes to catch up with their orders, especially for second-tier players.
Touch panels are currently suffering the most serious shortage due to Apple holding control over the capacity of major touch panel makers such as Wintek and TPK, and with U.S.-based RIM, Motorola and Hewlett-Packard (HP) also competing for related components, second-tier players are already out of the game, the sources noted.
So called "second tier" players are seemingly unable to obtain supply due to the high demand from Apple and other companies.
Apple had previously revealed that they had prepaid $3.9 billion to three companies in order to guarantee long term supply of a certain component, but stopped short of revealing which one.
This news seems to further indicate that Apple spent its $3.9 billion investment towards securing LCD supply for its future products, according to MacRumors.com.
