He missed talking about the poor extensibility of pandas. It's missing some pretty obvious primitives to implement your own operators without whipping out slow for loops and appending to lists manually.
Yes (mostly) is the answer. You can use arrow as a backend, and I think with v3 (recently released) it's the default.
The harder thing to overcome is that pandas has historically had a pretty "say yes to things" culture. That's probably a huge part of its success, but it means there are now about 5 ways to add a column to a dataframe.
Adding support for arrow is a really big achievement, but shrinking an oversized api is even more ambitious.
I thought that "The Particle Zoo: The Search for the Fundamental Nature of Reality" by Hesketh did an excellent job of explaining without dumbing down to the point of meaninglessness.
I am, although I do not use it as a daily driver, I have bare metal installs on two different computers. In my experience, it is very snappy, and always fast, except for some browsers, and wifi support for my specific wifi cards is there, and works fine, although not perfectly.
In regard to using it as a daily system, browser-wise, especially since Firefox has been ported, it works well enough. Webmail can be used fairly easily, but most of the email clients available only support regular pop/imap authentication, and not oauth.
But then, whether you can daily drive it depends on your specific use cases and hardware.
No, an extra ~17 msec of delay is not even close to the cause of this. The speed difference between older and newer UIs is still apparent even at 60 Hz.
I had a Blackberry Classic. The Android support was kind of garbage - but the physical keyboard was incredibly easy to type on and the trackpad was really helpful, and yes, the thing was built like a tank. I was once out running near some train tracks, had the Blackberry in one hand (I had no pockets and was probably using it for a stopwatch or a map or something), tripped on something, hands went out in front of me... and I broke my fall by slamming the Blackberry right into the steel rail. It was fine.
