if she can do the blending at home and everything else on the move, your options expand dramatically. namely, you can equip a laptop with an eGPU so you can attach a desktop GPU to it.
an ultralight used convertible 2-in-1 in the sub$200 region is plenty powerful for everyday use, drawing, whathaveyous. a $50 eGPU slot, a $15 PSU and a used 8 GB GPU in the $100 region will blow out of the water anything new for up to $1K and possibly beyond. double the budget for the graphics and there's nothing comparable but the top of Apple's line-up (no drawing on those, though).
