@gemlog Haiku's nice, by I haven't used it much, I've probably had used the original BeOS more. I have another laptop for such experiments: https://social.librem.one/@m0xee/109225441071185098
Despite having an only 20 Gb HDD, it has 5 (or even 6) OSes installed, including Windows 2000 some older Ubuntu that worked on Pentium 3, Plan9, QNX and either Haiku or Syllable, maybe even both. I don't use it much nowadays because one of the hinges broke, but I still have it. I've been doing the Fedi thing long before Fedi existed 😂
