It's awesome that Haiku has come a long enough way that it runs on my Framework out-of-the-box. Still ain't quite there as a daily driver, but it's very close.
Have you tried the newly-ported GNOME Web browser, mentioned in the release notes? It seems that it solves the "web browser problem" many users have complained about.
I haven't yet, but my daily-driver-blocking issues during my last attempt were more around stability. Much of it I think is the hardware (OpenBSD and Haiku both would spontaneously reboot on occasion; given that it was more frequent on battery, I suspect it's some quirk with the Framework's power management - or maybe there's something in the iwx driver that freaks out the whole machine), and some were likely attributable to being on nightly; I'll have to re-test with beta4 (and maybe the latest UEFI updates on my machine) to see if that straightens some things out.
The lack of a built-in solution for full-disk encryption is also a blocker for me. It's something I keep meaning to try and tackle (say, by porting over OpenBSD's FDE implementation), but I ain't quite comfortable enough yet with Haiku's codebase to even know where to start.
There's a non-built-in solution in axeld's DriveEncryption, but it doesn't support encrypting boot disks.
Probably we should try and incorporate DriveEncryption into Haiku itself and see about adding support for boot disks... that will require some discussion and agreement on how to change the bootloaders.
