SharePoint 2010, sounds great, but how is it going?

I have just heard about another small 2007 to SharePoint 2010 migration failing. Despite my own effort to force through 2010 SharePoint implementations for various reason I am being pushed back to 2007. This did NOT happen with 2003.

SharePoint 2010 is a nice evolution from from 2007, but I am not sure that end user benefits will make the movement to 64 bit (still very hard for companies) worth it.

I imagine in 2011 we will see a lot more movement to 2010, but it will be slower than the take up of 2007.
