Pre-ordering physical goods is fine, especially if you expect a price hike and supply limitations after launch. I wouldn't, but I can see how it would make sense.
It's the digital goods that make no goddamn sense to buy before they're out. They're not limited in supply, and their return window is often too small.
Do you even know why you're saying that?
Physical goods that need to be manufactured and delivered are literally exactly what you should be pre-ordering
