For web design I would go with a decent laptop but multiple screens are needed. Laptop should have Thunderbolt port or both hdmi and dp port to support multiple monitors.
If you are not preferring any extra monitor then at least you should have 17 inch laptop.
2x 24-27'' monitors + decent mouse, kb will be 4x more productive than a laptop for web design. Unless your team is working from home, I have to say you are wasting your money on laptops.
