That takes REAL GUTS (not logic) to jump on such a new OS so QUICKLY.
Wow, either a brilliant move or you'll be fighting drivers, applications and constant headaches for a couple of months.
(you'd think folks would learn after the Vista fiasco............)
Sorry, I don't think it's wise to jump into the unknown (seven keeps falling apart on us!) and with such massive changes, those of us who have lived through Windows since the days of Windows 286 and 386, 3.0 and so on may recall - vendors can't easily keep up, esp with MS will actually change the code you buy - it's not always what we see in the final RC............ last minute changes and patches have been known to creep into the code burned to the CD for purchase. Been there, done that.
We have simply had way to many things break with Windows upgrades, updates and patches - incompatability with things like ACS, print drivers, firewalls and so on make us sit back and watch for a few weeks, even months, before anything gets to production.
Symantec is VERY right to wait a bit after the final release, IMO. They've been burned before.
