◆ Linux
▲ Pros
- Unix foundation — real shell, POSIX tools out of the box
- M-series chips deliver exceptional performance per watt
- Tight hardware/software integration — fewer driver headaches
- Excellent tooling: Homebrew, Xcode, native Docker
- Retina display and premium build quality
- Strong security model: SIP, Gatekeeper, Secure Enclave
- Seamless iPhone/iPad/iCloud ecosystem integration
▼ Cons
- Premium price — MacBooks cost significantly more than equivalent PC hardware
- Limited hardware customisation — soldered RAM and storage on newer models
- Gaming library is a fraction of Windows
- Apple controls the platform tightly — ecosystem lock-in
- Some enterprise software (especially government/finance) is Windows-only
- Repair options are limited compared to PC laptops
Common zsh / Terminal Commands
▲ Pros

- Best gaming platform: DirectX, Xbox ecosystem, most titles ship here first
- Dominant in enterprise — Active Directory, Group Policy, Office 365
- WSL 2 brings a real Linux kernel inside Windows
- Wide software availability — virtually everything has a Windows version
- Strong accessibility features built in
- Good touchscreen and pen support across devices
▼ Cons
- Advertising and telemetry baked into the OS by default
- Largest attack surface — most malware targets Windows
- Registry complexity makes deep troubleshooting arcane
- Forced updates can interrupt work at inconvenient times

- PowerShell is powerful but has a steeper learning curve than bash
Common PowerShell / CMD Commands
▲ Pros

- Package managers (apt, dnf, pacman) make installs trivial
- Powers ~96% of the world's top web servers
- Highly customisable — pick your desktop, shell, and every component
- Privacy-focused — no mandatory telemetry by default
- Exceptional stability and uptime for servers
▼ Cons
- Hardware support varies — Wi-Fi and GPU drivers can be troublesome
- Steeper learning curve for users coming from Windows or macOS
- Adobe Creative Cloud and Microsoft Office have no native Linux versions
- Gaming has improved via Proton/Steam but still lags Windows
- Fragmentation — hundreds of distros means inconsistent experience
- Less commercial support for off-the-shelf software
