security cable for AlBook17

[silvo conticello]

I've got the AlBook17. Wow.

And now the next question.
I have just found out that I cannot use my current lock (the one I was 
using with the TiBook), a Dicota one: it is too large and I cannot use 
it if the computer is plugged in.
What security lock are you using around?
What about the kensington ones?

Thanks,
Silvo
