3Gb RAM, Octa-cores, android 5.0, and still no true multitasking topic

So we have devices with 3gb of ram (soon even 4), multi-core processors with over 9000 GHz, Android has hit version 5.0, but...... we still can not have TRUE multitasking. Most of the apps will just freeze if putted into background, and the so called "multitasking view" is nothing but a history of all the apps we have opened.
Coming from Symbian, which can do perfectly working true multitasking on just 256mb of ram, I find it...... kinda funny.
What do you guys think?
