Hello, why not? I go to work with my laptop, although everyone works for those that are provided in the office. As for me, it is more convenient to work on the instruments you are used to. The only thing I want to advise you is to buy a Silicone keyboard cover https://www.keyturepro.com/shop/p/macbook-air-keyboard-cover . This is a very cool protective layer against dust and other dirt for your laptop. I have one and I can work with pleasure, and then go away for a couple of hours and not be afraid of my keyboard.
