Is vista still vulnerable to hack?

It seems even the most expensive OS can't escape the wrath of this hackers! Windows Vista will plague users in coming months and years, a prominent security researcher warns, despite its security improvements over predecessor XP. Security bug-hunters are now turning their attention to the new platform and users should not expect Vista to be immune to attack, said Marc Maiffret, founder and chief hacking officer of eEye Digital Security. No matter this hackers will do just to ruin Vista, I think vista is still 100% better than XP.
