Just advocate NAV, we need to keep it afloat. I mean, bastardass pirates rip off NAV all the time, and though sometimes priated software is needed, for products I find really helpful, or very useful, and/or very nice I buy them. I want to support the companies that make good software, and that includes MS.
Piracy will always be around. To reduce my paranoia, I buy products that have to paid for. That way, I have tech support, etc. If I cannot afford it (even nice), I say it's nice to want or save up for it. Of all the useless crap I buy everyday, putting a few bucks a side every week will get me that little disk with the warm fuzzy feeling I did the right thing. That's just me; if others feel they wanna "borrow" stuff, oh well...

Like khakisrule said, you will not go wrong with NAV.
