Is there anything available to a browser to uniquely identify a computer, e.g. the MAC address?

AFAIK the only information like this you can gain from javascript is basic useragent information, things like IP address browser names/versions etc. Don't think there is anything in there that would allow you to uniquely identify them.

A MAC address is the only unique identifier in a PC.... Other info like IP etc will always change.. Saying that spoofing and MAC is also so easy...

Not really,

A cookie is just a set of key/value pairs that allows you to "remember" settings etc for a website. it doesnt identify the computer per se as required
