Not the OP but I got a 13" and a larger model Mac of the x86 variety when they were still reasonably young and even though I eventually got all of the bits and pieces to work it usually pays off to wait until a somewhat larger distro supports the hardware as well. That way you benefit from a much larger crowd of testers and once they have no more issues you should be good to go.
Moneywise it was definitely worth it, both machines are still working many years later and have been pretty much trouble free after the initial bugs were ironed out.
If I was in the market for a new laptop right now I'd wait for a bit and then pull the trigger on the latest model with broad support.
