Gotchas
- medium'Free forever' is a donation-funded promise, not a contract or company guarantee.¹
- mediumBusiness support is custom-quoted services, not SLA-backed enterprise support.³
- mediumSecurity patches follow Debian's cycle; official site has no standalone security page.⁴
- lowTrinity vs Plasma editions differ noticeably; test with live media before committing.²
Best for
- Reviving old laptops and desktops
- Low-RAM netbooks (2GB-class machines)
- Windows XP/7 refugees wanting a familiar desktop

- Teams needing MS Office or Adobe apps natively
- Anyone wanting polished, mainstream community support
