Absolutely correct, except I would say that a properly chosen laptop will be somewhat easier to fire up than a properly chosen Desktop.

No sure, as I never tried it on a desktop, but laptops seem more and more to utilize "standard" HW protocols of implementation, so on desktops it can be easier for HW to act up, not wake up, have strange bus routings etc etc.

With that being said, on a laptop you cannot change 80% of your hardware to evolve with time, or get that "more compatible but expensive right now" components, etc...

I only use laptops personally, for many reasons, this new one I got is my 3rd (and by far the best and most functional hackintosh) but with all of them, and this is scary to say the least, worked way more efficiently than M$, even with some HW limitation I encountered in the past.
