Even though I don't think any distribution of Linux is ready to provide me with the functionality, in our business environment at work (including access to Netware servers), that Windows has slowly developed over the years, that doesn't mean it can't already work for me at home.
As such, I've decided to switch all three of my desktop PCs at home to Xandros Linux (with Codeweavers). No, SWMBO will continue with Windows and no, I'm not switching my laptop, yet.
Why switch these three? In my opinion, the threat of spyware has gotten to a point where the available tools are inadequate to protect me from such programs. Yes, I already use Ad-Aware, Spybot S&D, Spyware Blaster, and Microsoft's AntiSpyware (beta).
But even using all four, tests have shown that spyware can still get through. So I've decided to spend most of my home computing time in Xandros/Codeweavers. Do I think that will stop all spyware? No, these people have an economic incentive to adapt and evade. Hence, they will probably find ways to attack Linux users. But at least it won't be so easy (I hope). YMMV.
