I felt like a right noobie when one of my colleagues said he'd got a Pixel tablet via the Play Store and asked him how he'd won it.
Apparently I don't install and play shittons of games like them.
£500 was tempting to look into it further but as you say, that news pissed me off because I now know my mum is gonna install some bullshit that one of those guys might have picked up on.
That hardware giveaway thing is only available in couple of countries right now, US being one. Otherwise, one can be a Platinum member in other parts of the world and they would get nothing.
