I'll take off my OpenBSD hat for a moment to address something that's bothered me for a while.
People are quick to suggest a system is incapable of something; sometimes, these people have never even booted the system they're criticizing. Yet they seem to magically know its limitations.
People denounce Linux in many areas, from gaming to photo editing to user-friendliness. Realistically, Linux is sufficient for most people's needs. If Linux is good enough for a 77-year-old grandma with dementia, it's probably good enough for you.
Usually, I find that mindset is the underlying reason for perceived deficiencies. Remember that Linux is NOT Windows.
For any of these categories, feel free to use the “List of Applications” ArchWiki entry as a supplementary resource.
“Linux can't game.“

“Linux isn't user-friendly.“
If you're still not convinced that Linux is good enough for your needs, here are some places you can find Linux:
