Items paid for by the company are property of the company and need to be reported with serial numbers etc. to People Ops for proper [asset tracking](/handbook/people-operations/sop/#asset-tracking).

Running Unix makes it easier to work with git from the command line so we strongly recommend against Windows laptops. WebEx screen sharing does not work from a Linux platform while it is one of the more common conferencing tools used with customers that we all need to interact with from time to time. Additionally 1password doesn't have a native client for Linux and the web interface in Firefox is not that good. If you have strong reasons to want to deviate from this guideline just ask your manager.
