Latencies bellow 16ms require a refresh rate higher than 60Hz. For 9ms you need at least 90Hz. Don't know many who do that. Specially if you take in consideration the battery hit that the faster update rate requires.

Don't those latencies add up? In the worst case 60Hz + this new pen will add up to (16 + 9) 15ms of latency, right? If the screen refreshes at T=0,16,33,50 and you create input at T=8 then the input will be processed at T=17 (8+9), so you will need to wait for T=33 before it show up for a total latency of 25ms (33-8). Which is a lot better than the potential total latency of 36ms with a 20ms pen.

People seem to be down voting without explaining.

Refresh rate isn't latency. Though you are right that you do have to wait for the screen to redraw.

There is screen latency as a completely separate number though, and those would add up. Many lcd monitors can have up to a 20ms latency. And those numbers would add up like you suggest. It's why gaming monitors can charge a bunch for their 1ms latency at 60hz.

It is also possible to have 120hz and 20ms latency. The numbers are not related.

I don't know what the iPads screen latency is.

now that both the mouse and the local storage work, can we finally code on this thing with a real local codebase and server?

What's old is new again! Mac OS became Mac OS X became OS X became macOS. iPhone OS, whatever it was called on the iPod touch and iPad OS merged to be called iOS, and now there's a new iPadOS.

No, the OS on iPads and iPods Touch was always called iOS - the OS was only called iPhone OS for a very short period of time.

I owned a 2nd-generation iPod touch during the “iPhone OS” era. It wasn't always called iOS. I'm not actually sure what it was called on the iPod touch though. I found some old reference on Apple's site to “iPod touch FW 3”, but I don't remember how much Apple explicitly mentioned it ran iPhone OS.

what's the solution? not implement multi-finger gestures due to complexity and just omit the feature altogether? I'd rather have those capabilities? My drawing apps on iOS all have tons of multi-touch gestures. I appreciate they are there.

Making things discoverable and easy to learn is an art in its own right, completely separate to the art of programming.

Yes and few are better at this than Apple

Honestly these new changes (esp. the second monitor for MacOS support, if it works well) will probably finally get me to buy an iPad. This all looks very good to me. Real file system browser; much better multi-tasking; closer integration with macbook.

The “file system” is not new, the files app is at least a year old. What they added now was just zip support (really needed) and USB sticks (I don’t care but many love this).

Don’t listen to all the whining podcasters that claim that ipad doesn’t have a file system. The files app and its integration into many apps works amazingly well, especially in conjunction with icloud drive. And you can access the local directories, so you can put a video file in the VLC folder or a PDF in the Acrobat folder. You can of course also AirDrop to the ipad already into these apps, but if you want complete control.

Guided access is great. It means my 2 year old can watch a video or play a game without worrying about her getting into anything else.

A 2 year old should not be watching TV and playing video games.

Says you. There's certainly value that TV or video games can give young children.

Oh, I dunno, it wouldn't surprise me if iPadOS is a step in that direction, and some future laptop runs... iPadOS and there is no more MacOS.

So a Chromebook move

With the ability to run full Google Docs in Safari, I don't really doubt this.

Never trust rumours. Rumours are tinged with bias. Rather, prefer to trust the horse's mouth and its history. Apple has always said they wouldn't merge macOS and iOS, but they have a history of bringing iOS frameworks to macOS for consistency (AVFoundation was a big one). Rumours are the fodder of those who cannot be bothered to learn about something but want the air of clairvoyance to impress friends; they are the l…

Rumors are spread by those who test the waters, usually.

Sometimes. But there’s never been any rumours about merging iOS and macOS, and Apple has always said the opposite, again and again.

The one you want is PCalc. It isn't free, but it's not expensive either.

I'm not sure how to ask this without it sounding anything other than genuinely curious, but it is: why would you spend money on a calculator app? What does it offer that other (free) calculator apps don't? Are free apps just so crippled that you need to pay for something full-featured and/or without something like ads? I'm not familiar with the iOS/iPadOS ecosystem.

Why would you NOT spend money on a calculator app if it’s better, or you just fancy it?

An iPad pro costs 1000 bucks and your time is probably worth around 100 bucks an hour, so if an app is good and costs less than 25 bucks you shouldn’t even stop to think before buying it.

A person with a well paid job that thinks twice about paying 5 bucks for anything he could potentially use for work even once is doing it wrong.

Why would it be important to know? Previous situation was already industry best (comparing other tables, Wacom, etc), the new one is several ms better.

Amazing. The top level comment is about improving performance even when many people say it isn't important. Someone says it would be nice to get even lower, and you say it isn't important. Full circle in three comments.

Yeah, wrong.

Someone said "I want to know end to end latency", to which I comment that it isn't important to know this to consider this a positive improvement, given that there's a measurable marked reduction in latency.

Never said improving performance isn't important. Maybe read the comments carefully top to bottom once more after the morning coffee?
