Samsung's new line of tablets will go on sale in the U.S. on Feb. 13.
Samsung Electronics Co. began taking orders for the devices on Tuesday. Announced at the International CES gadget show in Las Vegas last month, the new tablets feature touch screens that are among the sharpest available.
Samsung is also making models with screens measuring 12.2 inches diagonally -- larger than the main iPad and other full-size tablets.
A 12.2-inch Note version of the tablet comes with a pen and starts at $750. A pen-less Tab version costs $100 less, but won't be available until March. Samsung is also selling an 8.4-inch Tab version for $400 and a 10-inch Tab for $500. Both will be available this month.
