As a person who has been burnt by overpowered processors in laptops, I'd like to advise you to search for thermal throttling issues and look at the out of the box temperatures.

Even if the laptop works fine, the temperatures could get worse after a couple years of use. You might often need to change the thermal paste and clean the heatsinks and fan.

I would suggest waiting a bit more for extensive tests. OTOH if money is no issue, I'd go for it. i9 in a laptop sounds really cool.

What you don’t like exchanging all your ports for dongles? And the crappy keyboard? Or my favorite “Remind me again later” Because who would ever want the ability to say “no”
