Logitech eschewed mechanical switches in lieu of a large dial at the top of their wireless Craft keyboard, similar to the Dial found on the new Surface from Microsoft.  The Tech Report gave it a try in this review and found it to be flexible and useful.  It can be used to switch between contextual options in Photoshop, to change your font sizes or themes in Word or even to navigate Excel spreadsheets.  There are some applications which do not respond to the Craft yet and the extra power required by the Crown limit the battery life on the keyboard so the Craft is not perfect.  The keyboard retails for $200 so it would be worth your time to read the review and ensure the programs you use are compatible with the Craft; if they are then this is well worth your consideration.

"Logitech's Craft keyboard promises creative types more direct control over their workloads with a big, tactile multi-function dial integrated directly onto the device. We put the Craft to the test to see if it turned our creative juices up to 11."
