It seems internet commenter dismay that Google's Chrome OS notebook, the Cr-48, lacks a Caps Lock key may be premature. Although the notebook does indeed put a dedicated search button where Caps Lock would normally be found, according to the Chrome OS notebook "getting started" guide, you'll be able to switch back the functionality in the platform's settings.
"If you really need Caps Lock so you can post an INSIGHTFUL COMMENT ON YOUTUBE, click the wrench, click Settings, and then go to the System section to change the Modifier Key from a Search key to a Caps Lock key." Google
The Caps Lock isn't the only key change Google has implemented. Where the function key row would normally be found, Google has taken a leaf out of Apple's book and instead used those buttons for more everyday controls. Left to right, you have Esc, Back, Forward, Reload, Full Screen, Next Window, Decrease Brightness, Increase Brightness, Mute, Volume down, Volume up and the power button
The search button automatically pulls up a Google search in a new tab, probably a sensible control given that Chrome OS is all browser-based. Meanwhile the trackpad is also like on Apple's MacBooks, clicking all over its surface and using two-finger taps for the contextual menu. More on the Cr-48 here.
