Travel insurance for 2 year old mac book air

So there I am, trying to buy some travel insurance that will include my 2 year old mac book air in the event that someone tries to relieve me of it and I can't buy any.

Every insurance company I go to says that if my lap top is over 15 months old, its uninsurable. Any suggestions? I do love my mac book air - and I'm a writer so I like to travel with it. Does anyone know of any insurance companies that will insure it?

How about your home owner's insurance? Most home owner's policies can be adjusted to include items like computers by a special rider or schedule.

Thank you for the reply Chscag, my home insurance will be my next port of call. Good suggestion.
