Crucial T&Cs upfront: you have to vote for all the T3 Awards obviously, not just the gaming bit, to be in with a chance of winning one of 5 Acer Cromebooks, and the offer's only open to UK residents. You have until July 9th to vote.
So that's the boring bit out of the way. Now, head over to the T3 Awards page and you can cast your vote on a range of techy options from gadget of the year, through to TV of the year, phone of year, car of the... 'of the year' is the overriding theme here. If it's got buttons you can probably vote for it.
Most relevant to your interests will be the gaming product... of the year. That lets you chose between the following: Nvidia Shield Tablet, HTC Vive, Nintendo 3DS XL, Oculus Rift Crescent Bay, Samsung Gear VR, PS4, Xbox One, Wii U, Alienware Area 51 and the Razer Blade laptop. Pick your favourite there, as well as in all the other categories, then you can enter the prize draw for the Chromebook
