I don't trust free anymore, at least when it comes to software.
I can't think of any free software I've downloaded in the past (unless open source such as Audacity), but aside from open source, I can't think of any free software I've downloaded on computer that went well.
Always bugs, always and eventually you gotta 'buy', for better service and or virus or worse.
To me, better to just buy what you want, why?
1. Cause then you have chain of accountability, a receipt, something to follow, to track if things go wrong.
If somethings free, than they're not obligated to share anything with you, since it was free you have no legal ground to stand on if things go wrong.
I had to learn that the hard way.
So now, if there's some technology I want, I totally resist the 'down load for free' BS, and just buy instead, and as such things go much more smoothly.
