I do not use a laptop for audio production , but many here do........... However

I think perhaps you are going at this from the middle as opposed to from the start.

Start with: what is the intended use/es

First does it have to have portability ? If yes, then laptop by all means.....

If no, then probably no need to pay extra for up charge for laptop compared to a desktop

Todays powerful laptops will handel most home audio recording/ mixing with ease. BUT That said, you will pay more in terms cost/performance ratio for the laptop.
