The $129 Acer Iconia One 10 reminds me of the $50 (or £50 in the UK); it's not good, but it's good for the price. The price roughly converts to £100 in the UK and AU$170 in Australia.
It's a lot cheaper than any iPad and $100 less than another cheap 10-incher, the Amazon Fire HD 10 ($230, £230), which has the same screen resolution. The $200 (roughly £130 or AU$255) Lenovo Tab 2 A10 is the next best thing, offering a sharper screen but not much else.
The Acer's front-facing speakers are a great addition (since most tablets have them on their edges, making them easy to block) and they sound crisp and clear for movie dialogue. Unfortunately, like most tablets, heavy bass in music sounds muddled.
Its sub-par screen makes it a less desirable candidate for anyone interested in using it to watch a lot of video. HD video just doesn't look as sharp as it should and pixels stand out like a fresh pimple on a forehead. Also, its maximum brightness level is on the dim side and the screen is very prone to reflection.
For a tablet as cheap as the Acer Iconia One 10, the lackluster build quality didn't surprise me. The plastic back and the angular design looks kind of cheap and it feels like it might break if you squeeze it too tight.
The tablet runs smoothly when doing basic, casual tasks, like checking email and browsing the web. Big games like Hearthstone and Asphalt 8 take their time to load. Once loaded, the games run rather smoothly, save for some slow frame rates if downloading apps or files in the background.
