Setup is what it is all about
Unless you are wanting to get involved with configuring your router and dealing with the configuration in general, IMO there is no question that Hamachi is just simply the best way to go. Quick and easy. I've tested and used it and bottom line---it just works.
The funny thing I see going on here is the same thing with Microsoft's AntiSpyware program. Users like myself have been using the product before Microsoft bought them out and were disappointed when MS used it as a bait to encourage users to become ligit. with licenses.
