Was giving 7/10 it for image quality another April Fool joke?

Good to read a review that takes into account the price and the target market of the camera. The mark-down on build quality is well-deserved: there is no excuse for making plastic mouldings that do not meet and hold neatly and firmly. Canon have made a minuscule and inappropriate "economy" on that one, even at this price point.

"There are much better cameras available for just £20 more"

What are they?
I have the impression that you have taken this test a mistake and you are not able to evaluate it through. You have made ​​some macro photography? You have compared the series of the same Canon 2000 and 3000? The A490 has superb image quality and superior digital cameras that constantly 4 -5 times as much. I'm sorry, but if you make these comparisons do not mind that it is a camera for 50 euros, you can not judge it. For me it is a 10/10
