2 years ago we bought an Acer 15.6" laptop. At the time I was aware of the hearsay that Acer may not be the top brand but as a laptop is likely to be dropped, lost, stolen, trodden on, IMO it's best not to overcapitalize, and the Acer price (AU$470) was just amazing for a full-featured machine.
Fortunately it's still going strong.
2 months ago, I sourced another laptop for a client. This time a full-featured Celeron T3100 HP/Compaq 14", again less than $500.
My point is that while polls like this are a possibly-useful expression of collective opinion, and a favourable result may instigate a brief quiver of excitement to those who own one of the "better" brands (though, note how close to being "shoddiest" HP and Dell are on the pie chart), the results are so simplistically expressed without context in regard to the purchaser's requirements or financial resources, drawing hard and fast conclusions may be too big a step.
