The Apple Blog has their Windows 7 RC: Reality Check Edition, which is a fairly fanboy-ish look at Windows 7. They do reference legitimate articles when pointing out things like sluggish performance, edition confusion (even Paul Thurrott things this is stupid) and the XP compatibility issues, but it's a fairly cynical look. Some people I know have run Windows 7 for a while now and find it just fine.
That said, we'll see how it goes when things actually get released late this year.
