Paddles, at the time there were about two years where the tax rules allowed salary sacrifice for a laptop, (you're right, I think it was to promote use of technology at home), and provided you used it for work, then the ability to depreciate it remained. I just happened to be in the sweet spot of having the right number of kids below school age and a salary that placed me right on the edge of losing the Family Tax Benefit. It really was a case of all the planets aligning, and I'm guessing very few people probably figured it out, let alone acted upon it.
The salesman at Harvey Norman was sure confused. The conversation went something like this....
Salesman: "How can I help you, sir?"
Me: "I'd like to buy a laptop."
Salesman: "How much were you thinking of spending?"
Me: "As much as possible."
Salesman: "Here's our most expensive model, I can probably take 5% off that price for you."
Me: "No need to do that, I'd prefer to pay full price."
Salesman: "Certainly sir, and is there anything else I can help you with today?"
Me: "Yes, I'd like to see your most expensive Pocket PC." (You were also allowed a portable digital assistant at the time.)
Salesman (trying to hold back his grin): "Right this way, sir!"
He had no idea what was going on, but I guess was happy with his commission that day.
