I do IT for local businesses in Denver. I build workstations and servers, do hardware upgrades, networking, VPNs, firewalls, virtual machines - anything a business might need. Windows and linux. Any tech worth his salt will have learned how windows works and how to repair it. It is possible to repair. Same is true of any Linux technician. My first 'real' computer was a Fat Mac, so I still love a good GUI. And Windows has a nice GUI.
