A CNet article notes that Apple applied for a trademark for the term "Mactel" through the US Trademark and Patent Office.
The Mactel trademark is described as follows:
computers, computer hardware, computer peripherals, computer software, integrated circuits, circuit boards, microprocessors, semiconductors
Whether or not Apple is planning on using this term or is simply protecting it from future generic use is unknown. A recent poll revealed that users were generally split on what term to use to describe (in conversation) the upcoming Intel Based Macs.
