My Note 3 (3GB of RAM) and my Tab S 10.5 LTE (3GB of RAM) beg to disagree...
On both of them *I can actually multitask* (not to talk about the fact that Android has REAL multitasking and Samsung devices have MultiWindow capabilities...) and I can happily *keep open multiple tabs* in the browsers I use without the slightest problem and without the constant reloading and without losing zoom, position in the page and inputted data like on Apple devices.
1GB of RAM should be a deal breaker for anyone but very light users and gamers...
Did you not read through my post? 3 GB isn't possible for a single chip.
