I do not enlist here what parts missing for me to get Haiku R1, as I think the way that waddlesplash follows now is the best.
I mean if the stability and reliability grows more in case kernel and userland it’s better for everyone who uses Haiku as a daily driver, just as me.
I admit, I do not use my Haiku driven PC for work activities right now - actually I have no more IT or IT related working tasks where the weighing of uses cases are different.which features available in an OS, but all others than work : yes, I use it. Including government sites’ usage where I could administer documents and taxes, so not all the funny parts of my life, and entertainment, but important and serious ones
Since Beta4 I can install and boot Haiku reliably - that is the most important thing in it — as a daily driver.
When Beta5 was 1-2 months came around the corner … I switched to Haiku Nightly, I had not done clean install, but upgraded both nightly and beta version , and around holidays I could migrate onto an 512 GB USB thumbdrive in both cases, so now I have backup in a Beta5 key, and also have 2 backups in same system on a half capacity drive as well.
So backup restore question may solved.
To get R1 the community needs patience, as you could see many seemingly independent development matches surprising fruits … vice-versa in the last 4-5 years.
This way have VPN support, faster network, a debugger for devs, more compatibility layers … and yeah, of course, browsers.
Personally if I can take a mention about it : Haiku R1 targets BeOS R5, and beyond … I think the multimedia shold be targeted better, which includes optical media support as well, some old stuff like midi format (that I do not clarify here what I mean on it I may post a theme about it as lastly I hunted to play it conveniently). That way a computer could be used for offline usage - not needing a network access basically if the media is present in the storage or removable storage, and of course if someone wants on a media server even which might not accessed via Wifi LAN…
I understand nowadays a computer with a network access is a must for many people - especially due to modern services and consuming digital content, however if you learn/study something … people may use their phone if network is a must.
Haiku also targets a personal usage desktop OS, so it requires that to all of us accept that this way Haiku must cover very different interests.
We must be patient what part of an OS how important and for which goal need them in Haiku.
Some for daily driving and some for retro computing that also a huge area … I mean some just want to add a new chance for a hardware dusting on a shelf, but hard to left away due to belonging memories or got from a friend … or some of us thinks that other people would learn things how it is working, how they can use it …
I’m a bit skeptic about it lately, so I just lightly laugh/smile on people here envisioning crowds wants to learn Haiku. Some people not even learnt their smartphone, so I do not mention their PC - envisioning crowds switching to Haiku … a bit utopistic, especially how the conveniency of persons beeing growing.
A word like a hundred : with patience. 
Week by week interesting developments starts.
Lately a chinese developer shared that :
he/she had begun porting Haiku 64 bit freshly …
targeted a MIPS processor derivative, chinese manufactured processor family - LoongArch.
