Will MS Keep On Top For Security In VISTA

I've read on various websites about all this security talk with VISTA and there having to re-write about 60% of it. Mostly probably for better security features and the fact that there boffins have just rushed 100% of crap kept 40% of it to re-write the other 60%.

Now when say a bug or security flaw is announced or found by someone who dosn't work for MS. How long do you think it will take for them to fix it and will they be more concerned about VISTA than XP once it's out.

Makes you wonder if all the new op system crap is worth waiting for all this so called rubbish.

I doubt things will change at all. MS is MS, there will be security flaws that everyone knows about long before the patch comes out. I doubt anything will change that.
