Realistically I don’t expect the 2nd gen to be faster. I expect them to fix problems – if they had uncovered such with cooling, components sitting at each other interfering (like many iPad Pros: when Bluetooth is on, your WiFi will occasionally stutter _hard) or any build / motherboard problems in general.
A few weeks ago my new iPad M1 arrived, but I watched a few videos on YouTube compares doing tasks in both MacBook and iPad, and it seems pretty clear the iPad is a good device, but Apple put a limitation on it.
It was possible to use your iPad with a few limitations, and you need to use a remote machine to do your hard work.
And I had a good experience with Apple Pencil 2 gen.
I decide to use my iPad as a complement to manage my study, take my notes, manage my agenda and many other things. It is a better fit to use the iPad with the pencil.
For I can tell and following a bunch of rumors, the 2nd xM’s version will put more cores because getting grow with memory ram is thought though, and we will continue seeing with maximum 16GB ram.
