No rush at all. This release is what Windows Longhorn (that became Vista) was supposed to be. The problem is that as usual, Microsoft couldn't deliver on the 'vaporware', and after two years of delays, they cut their loses and put out in inferior product.
i have no doubts what-so-ever that Windows 7 will be the true successor to Windows XP, and Vista will become the Windows ME of the NTFS.
FWIW, i really didn't have many problems with Windows ME either, but was aware of where the problems would happen.
SO, 7 is "Vista fixed" then. I have a friend who says he buys every other desktop operating system MS puts out. Think about it:
Windows 2 - crap Windows 3.11 -good
Windows 95 - crap - Windows 98 workable
Windows ME - horrible - Windows XP - very good
WIndows Vista - not so good - Windows 7 - the best so far
He also only buys the server O/S after at least two or three service packs.
