site:example.com and Site:example.com show different search results?

I was amazed to find this today by giving: keyword site.example.com shows all urls for example.com
wereas keyword Site.example.com shows all urls for example.com + related websites.
Anyone find the exact difference here ?

Future - Your post and your title here differ in their syntax, but I'm assuming that you're asking about the Google site operator, followed by a colon, and what happens if you capitalize the S in "site", as in....
keyword site:example.com keyword Site:example.com
The site: operator is case sensitive, and when the S is capitalized, Google treats the query not as a site: operator query, but rather as a search that includes the word "site" as one of the search terms.
I've never found official Google documentation to confirm that the site operator is case sensitive, incidentally.
I should also add that, on my machine anyway, if I do one of the above searches right after the other, the new Google ajax interface isn't always responding to a case change immediately and I sometimes need to refresh the page after doing a search.

Yes, results were different. Very interesting observation. This is the first time I'm noticing it!

in the very small sample i ran [Site:example.com] results were similar to [Site example.com] with a small increase in reported results for the latter. what really surprises me is the difference in reported results between [Site example.com] and [site example.com] in a few of the cases i tested. i may try some more testing here later to see if i can discern any pattern or explanation.
The good thing is, Site:www.example.com shows other sites that are using your images. Just like the old days. Makes it easier to find people stealing your work.

Theoretically possible, of course, but in the tests I ran, results are generally more like what Lame_Wolf reports. You want to try this with a domain that's likely to be mentioned on the web beyond its own pages. If you try a few domains of different sizes, chances are you'll be seeing the differences.
Also, to assure yourself that there's nothing mystical about [site example.com], try searching [example.com site]. Number of pages returned should be close, but because Google estimates this number, it won't always be exactly the same.
