Apple has four new Mac vs. PC ads now playing on TV, none of which address any of Microsoft's recent commercials, which include a series of "I'm a PC" ads that claim John Hodgman's PC character is a cliché and a new series of ads in which people are given a budget to buy a computer and never select a Mac. All of them are available for viewing at Apple's web site.

In "Biohazard Suit," PC worries about the viruses and other malware that plague the Windows platform, which he says have tripled over the past year. Trying a different tactic, PC says in "Legal Copy" that PCs are easier to use than Macs, which results in a legal disclaimer along the bottom of the screen; it grows as he talks. 

"Stacks" touts iPhoto's new facial recognition feature, which has been available on the Windows side but doesn't come preloaded on a new computer, as Justin Long's Mac character points out while PC flips through stacks of photos one by one.
