Hi, does anyone know what the Microsoft Store's maximum trade-in value for a MacBook Pro is? I don't know my model number by heart, but it's a late 2013 quad-core laptop clocked at 2.6GHz, and it has 16GB of RAM and a 1TB SSD. I was considering trading it in for a Surface Book since I already have another quad-core laptop, but I don't know. I'm torn between unloading the Mac for Surface Book or the HP ZBook Studio, which sounds like the perfect computer for me.
