It is a decent laptop for a semi-laptop. Remember you must always use a wall outlet when editing, especially with MB use and it will be around 4 - 5 times slower than a desktop, so I assume you just like different wall outlets to get a laptop.
And in comparison to a Macbook Pro ? wich would be the best ?
Definitely the MSI, not only because the price is less than half of a MBP, but also because it offers better specs in the basic configuration and offers much more expandability.
