The slides were posted on a overclock.net but their photo bucket is overdrawn. The photos can be viewed at Ars Technia though.
Microsoft as part of windows 7 training is encouraging employees of Best Buy to slander Linux based products.
The slides I find most laughable is the updating one, as Linux has a much easier automatic update system then Windows at this point. They also exaggerate problems such as hardware compatibility and size of software library.
My personal experience has taught me that at this point, the only leg Windows can really stand on is gaming. All other forms of computing are better served on other OS's. I suppose there is a bit of slowdown in Flash rendering shared by both Mac and Linux based systems but that should become moot once HTML5 makes flash unnecessary for video playback (this should encourage Adobe to make some much needed improvements in their software).
With Google's own OS still gleaming on the Horizon and Microsoft feeling hurt by the Apple ads I suppose it only makes since to lash out at the competition. The sad truth is though Microsoft has over 90% of the market and it will be hard work for any of the competitors to take that away from them. Microsoft has long been the provider of the inferior product but their marketing giant just can't be beat it seems. So I suppose it just strikes me as petty that they are trying to use their market position to slander the competition.
Windows 7 will be a marked improvement over Vista. However it seems to me that Microsoft is always playing catchup when it comes to security and software features these days.
