Someone at Apple Australia has stepped in and resolved the wait / non-response from the company, following a second fax, this week.
Since being advised Apple had given up on repairing the machine, a couple of weeks ago...
- I returned all packaging to the service centre, for Apple to arrange collection
- A Customer Care person contacted me to offer a replacement MBA . I refused as I'd prefer to get a Gen2 MBA once it is bug tested.
- I had not heard back from anyone at Apple
- This week I faxed an updated letter, requesting an update from Apple.
- I had not expected an instant response, but Apple had not even acted to collect my dead MBA and packaging over the week.
- A helpful Apple person contacted me yesterday, to advise that she would look into the case, following my fax.
- Less than an hour later I was advised by phone that the refund was arranged between Apple and the retailer, for my collection.
- The refund process was a breeze as a result and I am happy once more.

I can now cancel my complaint with the Department of Fair Trading and keep an eye out for 'new MBA' news.
I picked up a Compaq laptop as an interim stopgap until then.
Thank you for your help and support.

Does anyone else have stories, good or bad, on their MBAs?
Thanks!
