Visiting again the British Library Humanities Reading Room last week, I had a major problem securing my laptop as it has no Kensington slot. I haven’t found anything useful for locking it except this free (car-like antitheft)Lockdown application. If you are not too much paranoid – it is a clever solution – and a lot of fun here back in the lab to watch the pictures it takes.
Addendum
Found some lock brackets here.
I found the website macbracket.com, and i ordered a bracket for my MBA.
