For snap multitasking, nothing beats the widescreens (16:9/16:10). I have two widescreens at work and one at home, and having documents/applications side by side is rather necessary for many work environments.
Also, Kristalsoldier, you should read the threads about Surface 2's Tegra 4 passive pen capabilities; I'm willing to bet NVidia will continue to support the DirectStylus in their Tegra processors, so adding an active digitizer like Wacom's (more licensing cost and probably power draw) would be redundant and unnecessary on a Surface RT-type device.
Although the Wacom Feel IT is not the equal to a graphics tablet it still is more than likely considerably more accurate than any capacitive solution. Although I would welcome ANY improvement over the less than satisfying stylus performance on my RT I still want to see an RT with an Active Digitizer. I have a Samsung Ativ 500 and the Wacom Digitizer works beautifully and makes OneNote far more useful than on my RT. Again any improvement would be welcome but a capacitive solution will never equal an actual digitizer layer.
