It was shockingly performant, especially with anything graphical.
The difficulty was no apps.
Brings back fond memories, nonetheless.
I had the same experience.
Only few things came close since: QNX, my M1 MBP when it was new and a fresh MXLinux installation (no idea how they do it, maybe some low latency scheduler?)
Those felt similarly instant GUI-wise as BeOS did, while unfortunately current MacOS and Win11 feel glacial compared to it.
(Disclaimer: you can pry my still-functioning BeBox from my cold dead hands.. okay, I admit, I only use it a couple times a year just to be sure it still boots..)
Related: I've been enjoying, the Designed in California podcast [1]. Link below is "Part 3" wherein Apple is circling the drain in the mid 1990's (when I started at Apple, BTW) and is desperately looking outside Apple for the operating system they hope will save the company. Be (and Jean-Louis Gassée) look like they will win:
Everytime I have to re-find all of the adapters for the keyboard, mouse and monitor. Always amazed how fast it boots when I do get it going.
Well, how fortunate we are now, being able to do simplified coding through LLMs. AROS and Haiku and MenuetOS (etc.) could get a boost in software availability soon.
I was able to find a decent number of apps on BeBits but a lot of stuff was missing.
Ended up using Linux, but it was a great OS for its time.
Can you expand? What works well, what may need more work, what is not there...
