If you know a person uses Firefox, IE, or other - are you happy?

Or maybe you want to know that they use FF 5, or 6, or 7 +? IE 6, 7, 8, 9? Etc?

Or do you have to know they're using Chrome Firefox 6.0.2?

Just curious. I may, or may not, release my stats software (it's your typical, track what happens on your site) stuff. It's not up to par with some software out there, but I don't even need all the info some of those offer.

I track the basics (IP, hostname, Browser (to an extent), OS (to an extent), Referer, Entry Page, Country, etc). Good enough for me, but I'm always expanding it, based on the desire to have extra info. I still don't track the mobiles, but am working on it (thats where the "to an extents" come into play).
