existing users). Similar marks were recently rejected by the USPTO citing a "likelihood of confusion" under section 2(d). Despite expert analysis that the mark is "probably generic", Psion Teklogix issued cease and desist letters on December 23, 2008. This was heavily criticized, prompting the formation of the "Save the Netbooks" grassroots campaign which worked to reverse the Google AdWords ban, cancel the trademark and encourage continued generic use of the term. While preparing a "Petition for Cancellation" of they revealed that Dell had submitted one day before on the basis of abandonment, genericness and fraud. They later revealed Psion's counter-suit against Intel, filed on February 27, 2009. It was also revealed around the same time that Intel had also sued Psion Teklogix (US & Canada) and Psion (UK) in the Federal Court on similar grounds. In addition to seeking cancellation of the trademark, Intel sought an order enjoining Psion from asserting any trademark rights in the term "netbook", a declarative judgment regarding their use of the term, attorneys' fees, costs and disbursements and "such other and further relief as the Court deems just and proper". On June 2, 2009, Psion announced that the suit had been settled out of court. Psion's statement said that the company was withdrawing all of its trademark registrations for the term "Netbook" and that Psion agreed to "waive all its rights against third parties in respect of past, current or future use" of the term. Hardware Netbooks typically have less powerful hardware than larger laptop computers and do not include an optical disc drive that contemporaneous laptop computers often had. Netbooks were some of the first machines to substitute solid-state storage devices, instead of the traditional hard disk drive commonly found on laptop and desktop computers at the time. This was due to solid-state drives being smaller, more power efficient, and more shock resistant. Unlike modern solid-state drives, these early models often did not offer better performance. Almost all netbooks supported Wi-Fi and some supported Mobile broadband. Some also include ethernet and/or modems. Most netbooks used low-end, x86 processors focused on low power consumption. The majority of early netbooks typically used processors from the Intel Atom line, but some used competing processors from AMD, including netbook APUs, or VIA Technologies, including the C7 and Nano. Some very low-cost netbooks use a system-on-a-chip Vortex86 processor designed for embedded systems. A few netbooks used non-x86 processors based
