KEY vs TXT — Strengths and limitations
What each format does best, and where it falls short.
KEY Strengths
- Cinema-grade typography and transitions.
- Free and preinstalled on every Apple device.
- iCloud sync and collaboration across Mac/iPad/iPhone/web.
- Apple Pencil annotation and whiteboard modes on iPad.
- Exports PDF, PPTX, Keynote Live streaming for audiences.
Limitations
- Apple-only — Windows and Linux cannot open .key files natively.
- PPTX export loses some Apple-only effects.
- IWA binary format is opaque to third-party tooling.
TXT Strengths
- Universally readable — every operating system, every editor, every programming language.
- Zero metadata overhead: the file size equals the character count (for ASCII).
- Safe to diff, grep, version-control, and pipe through command-line tools.
- Immune to format obsolescence: a text file from 1970 still opens today.
- Tiny footprint for structured data like logs or configuration.
Limitations
- No styling, images, or embedded structure — just characters.
- Character encoding ambiguity (ISO-8859-1 vs UTF-8 vs Windows-1252) causes "mojibake".
- Line-ending differences between OSes still cause subtle bugs today.
