It's amazing. Take a look at my copy, xseria.com/mint. It's nice and clean, no flash is used, totally customizable and you can even make your own plugins for it. I made the 'Big Total' one For $30 its totally worth it.
Mint is good but the features are very limited, if you requier more details on your visitors then you should use an alternative, Google Analytics might be something for you then.
Actually, the only issue i have with it atm is there are no ecommerse plugins. I'm sure someone can come up with one but for now...
Mint is great! I use it on 2 of my sites for a fresh look at what's happening right then. For more detailed info and historical trends, I use the server logs. There's some great Peppers for Mint to that are very handy.
The only Analytic software that matches and exceeds Google analytics is Clicky. It has everything you could possibly need for a small to medium traffic site, up to the minute stats and even a spy feature that lets you see visitor actions in real time. It has both free and paid versions. The cheapest I have seen for a paid version I might add. I use Google Analytics on one site and Clicky on another. The spy feature alone keeps me on Clicky far more than Google A. If I had to pick a fault, it would be the maximum page view limit that Clicky sets. Currently it is set to a max of 100,000 each day.
Google Analytics is free and so I see no point in paying for other software. I currently run it on my blog, and it does all that I need.
I am also using mint, its really cool but don't know why i got large difference in page impressions when I compare it to awstats.
