Marketing BS vs Real World Experience
I Vista was rubbish. I didn't buy a new laptop with Vista, because I had read a lot of features were not as advertised. I won a competition and Microsoft gave me a laptop with Vista on it (seriously) and, in all honesty, it lives up to the reviews. If I could push a button and roll it back to XP SP2 and have all the drivers in place, I'd do so in a second, but at the moment I need it just to work (am using proprietary windows software that wont run under WINE, and yes, I know, dual boot, NTFS support etc..., but this is not my primary computer) and once I finish with it, it's so going Unbuntu. I've just had enough.
And it's all well and good telling people that this new piece of software has a brand new feature that keeps you safe, makes your life easier, makes it prettier and prevents malicious programs from causing problems in a little test environment, they are going to say "Great!" (and if they don't you just lose their video for the marketing campaign).
Yet once they get their new system home, have disabled the application control features because they broke their favourite software, none of their music or movies will play for "Security" reasons (DRM), the pretty user interface has disabled itself (again) because it might run slowly and they have to keep going through sub-sub-sub-menus to access options they change a lot that used to be three clicks away (but you don't need them anymore), they'll realise they have been sold a donkey.
