Thursday's CNET Update will beat the game for you:

The PlayStation 4 dominates today's tech roundup. Sony hinted at what the new system will be able to do, but held back from actually showing what the console looks like. (It's just a hunch, but I'd say it's a black box.) Also, Google releases its first touch-screen Chromebook, but the price is also a touchy matter.

Wednesday's CNET Update does a barrel roll:

Google wants you to fall in love with the idea of a computer on your face.

There can only be one CNET Update:

Tuesday's tech news roundup looks into the HTC One, the company's new flagship smartphone.

Watching Friday's CNET Update can earn you a trophy:

It's likely that Sony will show off a new PlayStation at its event on Feb. 20, and CNET's Jeff Bakalar takes a look at what to expect -- and what the PS4 needs. There is also a report of a new PS4 controller, with images obtained by Destructoid.

Thursday's CNET Update is reliving the '90s:

Apple is addressing two iOS bugs mentioned in today's tech news roundup. But one isn't so much a "bug" as it is an exploit to bypass a lock-screen passcode through a series of steps. Once bypassed, it's possible to make calls and listen to voice mail messages. Another fix is coming for those that use Exchange Sync. Some iOS 6.1 users were seeing batteries drain faster because it was excessively communicating with Exchange servers.
