What's the issue with AmigaOS 4? - Why does no one like it? - I'm just curious, cause I read some of the negative comments and since I don't know much about OS4 I wonder why it's disliked so much.
Mostly historical reasons, or a preference of other Amiga-like OSes.
Most of the OS4 users left Amiga.org a long time ago when it was decidedly un-OS4-friendly. If you go to other sites like Amigaworld.net and Amigans.net you'll find OS4 is - by and large - looked upon much more favourably.
Luckily A.org is generally a lot more friendly towards OS4 users now, but a few years back it used to be decidely hostile.
I stuck around because I like my classics and my OS4 Miggies the same, and A.org has always been good for classics.
