Pretty much my own views on Win8 after trying the preview version.
Interesting that the general view is two mismatched systems cobbled
together badly even if it is more slick and stable an OS - get the
impression of watching a car wreck in slow motion here

How fortuitous that Ubuntu will have all the kinks ironed out well
before Win8 hits. Linux on the desktop courtesy of Microsoft getting
it badly wrong ? Who knows !!
