Seeing comments like this “I'll never switch back to MS for what they've done in the past” always reminds me of this post from Hanselman http://www.hanselman.com/blog/MicrosoftKilledMyPappy.aspx

Companies have reputations just like people do (that's why we call them 'incorporated') and just like you can lose your trust in a person you can lose your trust in a corporation. This is not about Microsoft just doing 'stupid stuff sometimes' it is about institutionalized criminal behavior sanctioned at the highest level of one of the largest software companies in…
If you are referring to Microsoft's bundling of IE, that did not kill Netscape. It just buried the rotting corpse.
Before IE was bundled with Windows, it was sold in stores as a boxed product, right next to Netscape's boxed product. Going head to head in retail software stores (Egghead, CompUSA), IE massively outsold Netscape. This is what killed Netscape.
The reason IE outsold Netscape at retail was simple--it was a much better browser. Netscape introduced a lot of proprietary tags, which Microsoft included in IE. Microsoft also introduced proprietary tags, which Netscape often ignored. For the end user, the result was simple: IE correctly rendered more pages than Netscape. It was also better on resource usage, if I remember correctly, which was a much bigger deal then than it is now.
