This is my main machine if I work in Mac Office :

On this machine I have a 512 GB SSD drive. The MacBook Air is attached to a Wavlink UG69PD2 docking station with two iiyama 27 inch PL2730H screens attached with HDMI and a normal keyboard and mouse.

I use Parallels Desktop for Mac Business to run my virtual Windows and virtual Mac machines on my MacBook Air M1. This is really great software to run the operating system that you want.

I have also a Dell Optiplex 3000, great machine to do all your work on the full version of Windows. I have an external 27 inch monitor, keyboard and mouse attached to this mini PC. I can also do all my Windows work on my Mac but like to have a separate Windows machine.

Because I want to read my mail on my SurFace, iPhone, MacBook and on every virtual machine if needed I use Microsoft 365 Business Basic so it is very easy to get your mail on every machine you want and have it all Sync.
