Samsung is expanding its line of Galaxy Tab and Galaxy Note tablets with new Pro models focused on multitasking and productivity. The new Galaxy TabPro will be available in three sizes — 8.4-inch, 10.1-inch, and 12.2-inch — while the Galaxy NotePro will only be available in the 12.2-inch size. Samsungs goal with the new tablets is to better straddle the gap between a normal tablet and a laptop computer. The Galaxy NotePro and 12.2-inch Galaxy TabPro feature new four-pane multi-window multitasking, while all of the tablets offer multiple layered pop-up windows for multitasking.
