News of Apple's rumored tablet computer once again got fire when MacRumors revealed a possible trademark registration named 'iSlate' accompanied with 'Magic Slate', according to the reports the names were trademarked by Slate Computing, LLC in November 2006 which seems to be a proxy corporation used to secretly get the trademarks.
In delving deeper, however, we have discovered evidence that Apple is indeed behind Slate Computing, LLC and the iSlate trademark. The trademark application documents for the iSlate reveal the signatory being one Regina Porter:
Regina Porter happens to also be Apple's Senior Trademark Specialist as shown in her Linkedin profile. While we can't definitely pinpoint this to be the exact same Regina Porter, it seems beyond the realm of coincidence. So, not only did Apple obtain the iSlate.com domain in late 2006/early 2007, it also seems likely that Apple also filed for an iSlate trademark under a dummy corporation. Given that, it seems "iSlate" is very likely going to be the name of the upcoming Apple tablet.
