Depends on who "they" are. The ISP you connect to will be able to log
your MAC, IP and connection route. Anyone who is on the same network as
you could run nmap, determine your OS and possibly determine if you have
any holes in your firewall. If you have public passwordless shares on
your PC, someone could connect and browse the shares, potentially
finding pictures, letters, etc etc.
But all of this can be done irrespective of whether you're connecting
via (open) wireless or a network cable. If you're using an unencrypted
wireless channel then in addition to all that someone sitting nearby
could sniff all your traffic and with some skill and the right tools,
they could capture passwords, account names etc etc.

This is practically a FAQ. Use wireless encryption, only connect to
SSL-protected websites and if you're super-bothered set up a VPN.
