Actually yeah, I remember realizing the same thing a while back. 1 pound difference is about what I can perceive. Same with 1˚F difference.

A laptop that's a pound and a half is also very different.
But oh, if you're willing to say "and a half" you might as well be willing to say .7 kilo.
There's no real overall advantage, you just picked a couple very specific numbers. You can always pick very specific numbers to make any system look better/worse.

I don't think I can perceive a half-pound difference, but half increments are still nicer than needing the whole range of decimals. If I have to say 0.7 anything in everyday life, then it's not a good unit.
Pounds have a nice granularity for every day stuff: a 3 pound laptop and a 2 pound laptop are significantly different, but both are “about a kilo”.
On the other end, a gram is such a small amount that I can only perceive it in multiples, whereas I have a pretty good idea of how much an ounce is.
