The honest bit
I don't own this laptop. You'd be buying it.
Right now it's a spec sheet, not a machine in my bag. This auction is the pre-order: every ad space you take on the lid is a slice of the laptop itself. The A$3,740 floor pays for it; everything above funds the spec.
Once it lands, it becomes my everyday travel laptop — the one in my bag on trains, in airports, at cafés, on the road. I post those moments from my profile, and your logo is in the frame. That's the marketing: not a banner, but your brand, travelling — and for a sponsor it's 5–6 years of organic, founder-led exposure in real places and in every post, long after a paid ad would've been scrolled past.
Disclaimer. I currently don't own this laptop. All proceeds from the advertising spaces on the lid go toward funding this device. The aim is to use it as a travel laptop on the go, with photos on my profile and posts — those posts form the basis of the marketing. That's the story it's built on.
