Hi all. I recently purchased a Macbook Air and found that it does not have a Kensington Lock slot. How can I physically secure my laptop to the desk? I have heard of USB alarms. Do they work? Is there anyway I can attach a Kensington Lock to my Air without damaging it? What about the Maclock? I heard that they are not really useful. Some of you may suggest that I be careful and take it with me everywhere. But I am in an environment where I cannot do so. What choices do I have? Thanks.
