Because Im currently typing this on mine (1 GiB, android install) and everything is (very surprisingly) rock solid – page loading is very smooth, youtube playback is smooth as well (it can even play 4k videos no problem) and even gaming works flawlessly well (Haven`t went too far beyond PS1 games, but from PS1 and under it plays everything really well.). In short – It delivers a desktop experience at the expense of almost nothing with the power draw at that same level – 1W (best case scenario) to 3W(worst case scenario).
