I had my finger over the buy button for various Strix Halo machines for weeks.
I ended up going with the Asus GB10 because if the goal is to "learn me some AI tooling" I didn't want to have to add "learn me some only recently and shallowly supported-in-linux AMD tooling" to the mix.
I hate NVIDIA -- the company -- but in this case it comes down to pure self-interest in that I want to add some of this stuff to my employable skill set, and NVIDIA ships the machine with all the pieces I need right in the OS distribution.
Plus I have a bias for ARM over x86.
Long run I'm sure I'll end up with a Strix Halo type machine in my collection at some point.
But I also expect those machines to not drop in price, and perhaps even go up, as right now the 128GB of RAM in them is worth the price of the whole machine.
