Count me as one of the millions of Microsoft OS users who has little knowledge, or desire to learn, the ins and outs of registry manipulation, SDK's, kernal tweaking, etc. If I'm to spend $150-$200 for the latest version of Windows, I expect a trouble free user experience. From where I stand, Me, Vista and now 8 have been less than trouble free for many users. Fortunately, I've managed to ride the wave of reliable platforms - 98SE, XP, 7 Ultimate Home.
Were I, like Hajo, to spend upwards of $1k on a new computer and find hardware componants (which ran fine and smooth the day before) to now be the source of endless frustration, well.....I'd be pissed. Just sayen.
