interesting except you never know that a black hat hacker has not been exploiting this for 9 years and not sharing his exploits, bugs should be disclosed very soon because you never know how long someones been using said undisclosed exploit. if you find a bug don't you think others find it too. at the same time some company's release said products with that bug and just might have known about it when it was released and didn't want to address said issues.
anyway theres no point for software to ever be perfect if a company wants you to buy a new version. how many patches have been re-patched because they added new problems. anyway these are some of the main problems with closed source software.

Actual it sounds like if anything hurts microsoft its microsoft.
linux has found an area to be installed in netbooks but microsoft reactions is to give away products like window xp on said devices to prevent linux.

this is one example but from alot of sources microsoft has been discounting windows when faced with linux instead of competing in a healthy way.

so giving windows away to stop product ABC from happening is hurting them .... this is good there making the decisions (this could also be viewed as anti-competitive and abuse of monopoly power yet again too) eventually they will not be able to give away said products (linux is not going away and it keeps growing and changing faster)

also note office is there cash cow, well instead attacking why not make office for this new platform and compete (also the interesting thing is if they ported office to linux it would help lock in there formats and they could charge more for it and people that use it would buy it)

You can always ALT+ click a window in linux and move the whole program around. Its been in X for along time too.
