It's not the worst thing that they've ever produced - but i wouldn't suggest it for normal users who expect everything to work, because quite simply it won't all work.
the biggest complaints were:
1. the DRM attempts in it - they are just an annoyance rather than a realistic problem, i used the voice recognition today to tell it to download a TV program extract the rar files then play it back and it didn't complain once, lol
2. the bloatedness of it, realistically as long as you have a high spec PC it's not too much of a problem, but i does use huge amounts of resources for itself so it is a good idea to have lots spare as that makes the %age wasted lower, lol
3. the fact they are going for the "nice look" rather than a "practical and usable look" - which to be honest many programs are doing and people have to get use to it, i'm not going to happy about it but i'm sure in a few years time i'll have no choice but to have a computer with just 2 buttons on the keyboard because multiple buttons are "too complicated" and spend hours trying to type a single word because it "looks nicer"... lol (i seriously hope that's an exaggeration and not where computers are really heading)
