Could "Metro" be the next "Vista"?

When Windows Vista launched in November 2006 customers encountered numerous issues, mainly due to underpowered hardware, driver issues and incompatible software.

By the time SP1 was released in February 2008 most of the issues had been fixed, however many of the negative perceptions remained.

This is illustrated by Microsoft's "Mojave Experiment".

When customers were asked to rate Vista they gave it an average of 4.4 out of 10, however when given a demo and asked to rate Microsoft's "next OS" (codenamed Mojave) they gave it an average of 8.5 out of 10.

At the end of the experiment it was revealed that "Mojave" was simply a rebranded Windows Vista.

I see this phenomenon occuring online where commenters will fervently declare their opposition to "Metro", but when questioned they are unable to articulate what they believe "Metro" is... outside of "the new stuff".

Obviously Windows 8 suffers from none of the performance issues of Windows Vista when it was released (if anything it performs better than Windows 7), however as we have seen with the "Mojave Experiment", the quality of the product and the perception of the product are not necessarily aligned.

So my question is this; could "Metro" be the next "Vista"?

Are there enough "I hate everything new" people to cause a word-of-mouth perception problem when Microsoft releases Windows 8 or are these opinions simply being amplified by the online echo chamber?

If you do think Microsoft will need to deal with a negative-perception problem when Windows 8 is released, how would you suggest they counter it?
