Personally I do think there has been an improvement.
The reason I am thinking this is basically Mesh. Not having a go at them or anything as they sell a hell of a lot of PCs but we used to see a lot of bad posts. I have noticed in the past few months hardly anything about them so to my eyes it appears that they have seriously improved what service they provided before. Perhaps thanks partly to Davy who is they representative on the Forum. So well done to Davy.
And going away from any particular company it does seem to me that here at least we are seeing less posts from people about any particular manufacturer.
Now I'm not an expert on these sort of things but when we see far fewer posts from people moaning about poor service from any particular company, whoever they might be, that must be a sign that things have got better.
I'm only going by the postings in the Forum I must point out but it has to be a good sign.
