A very good friend has advised me to wait at least a year before upgrading.  He works in IT and as yet has never been proved wrong about trends etc.

If your company is ready to upgrade now, then I guess it would be prudent to get the latest software, however, if it's for home use, there are still some glitches/bug that need ironing out and it's best to wait for the SP1 to be issued.
