Depends on what you're working on I guess. We're focussed on AI research, working together with car and car parts manufacturers (BMW, Volvo, Audi, Continental, mobileye, etc.), robotics manufacturers like Kuka, ABB, Boston Dynamics, Kawada, etc., but also other autonomous systems with NASA/ESA and a few others. Others might not have those requirements. Our security research group is really a mix of Lenovo and Macs, I'd say the Lenovo/Linux guys are more "applied" research and those doing theoretical work (post quantum cryptography, etc.) are more on macOS.
