Multitasking absolutely sucks on Mobiles, I agree with you that the matter is pressing as smartphones and even more tablets now have enough Ram, CPU and screen for good multitasking.

On Windows tablets it is perfectly ok although I highly dislike metro's lack of windowing management:

Customize your screen with 3 metro apps (e.g. twitter, browser, Xbox music), switch to another full screen metro app (flipbook), Switch back to twitter and there you go, metro forgot you customized the screen and shows twitter full screen. What king of crap is that 18 months after windows 8 launch.

Apart from that though I am extremely impressed with the Surface 2 and multitasking with outlook, word, browser & apps is a given.

Re r00fus to me the back button, also on Windows phones, is a major ui design failure. On touch buttons it could change depending on context but it's impossible for hardware buttons.
