MacBook and Sam are to different purposes. Buying a SAm is good, but don't think you're going to replace your MacBook with it...
I didn´t mean to say that. I sold my MacBook Air (a somewhat useless device by itself). The replacement was not SAM, but something that has better UAE performance than the MBA (a Sony Vaio).
But the reason I wanted better UAE performance was: at home I was doing more stuff on SAM and wanted to have some of it on the road with me.

I am super excited about the X1000, but also a bit sceptical. I definitely won´t swap my ubercool UNICOMP keyboard for the AmigaOne model. Even if I am probably stuck with those ugly windows keys.
