I really don't think Microsoft's main product offerings are that bad. The biggest issue with Metro and Windows Phone is a lack of developer support - and I think a significant part of that is caused by a lot of the best developers being either Apple or Google "fanboys". Office remains excellent, Windows 8 is excellent at what it intended for - office productivity, games, VS development etc.

But the media hates them, OEMs mostly don't seem to care very much about making good hardware for PCs, Windows tablets and windows phones. To me this is at least partly a symptom of their image problem.

EDIT: I say this as an open source advocate - I would love it if Linux based systems became more popular, but I recognize the quality of Microsoft's products in terms of what they are intended for.
