Sport?? Eugh!! That's a bad word!
You're not missing out on very much at all, though I guess you can't access your PM's.
If you really wanted access to it, then when you get home tonight, register your home computer with a site called 'Logmein'. If you leave your PC at home switched on and connected to the net when you are out, you can then access Logmein at work and it will let you browse the internet (and all your personal files on your own PC) remotely.
It's free too :)
