Except I can't download a list of everywhere you've been, merely what site linked to my site. A pretty reasonable request if you ask me
Also Windows information, whilst OS isn't particuarly vital, screen resolution, colour depth and browser DEFINATELY are! I know, through stats that my average user is *still* 800x600, 65536 colours using MS IE 5.0.
Java version isn't terribly important to be honest. If anything the most important details are:
Browser and renderer version number.
Resolution.
Colour depth.
Referer, especially important for sites that monitor how they are doing in search engine referrals, advertising schemes etc. Also nice to see who is spreading the word, so that you can repay the favour.
Just my two euro cents.
