I wanted to bump this thread again, because there's kind of a new phase I wanted to add to my initial list, and that is the phase I'm in now and have been in for the last couple weeks:
6. This versatility is amazing.
The original iPad changed my workflow and was assigned several things that my laptops used to be used for. The Pro lineup in general, especially when paired with the various accessories available, took even more of those tasks on. Fast forward to the 2018 11" iPad Pro that I had before this--by the time I got that machine, I started using it for my actual job some days AS LONG AS I didn't have any conference calls or major multi tasking to do that day that required lots of apps to be open at once. If I was just babysitting my inbox and taking some random calls here and there, I didn't mind just leaving my Macbook Pro behind and living on my 11" iPad Pro for the day.
Over the last 3 weeks though, I have been pushing the envelope with my 2020 12.9" iPad Pro, and I made a pretty crazy discovery: I can now fully replicate my Macbook Pro workflow on my iPad Pro--at least the way I use my Macbook Pro when it's not docked on my desk to my dual monitors. With my Mac, if I'm away from my office and not using it with my dual monitors, I just set up Spaces, one that resembles my left monitor layout and one that resembles my right monitor layout. Then I just swipe back and forth between the two spaces.
With the 12.9" iPad Pro, I set up app pairings that resemble the same Spaces I used to use on my Mac. So one space might have Outlook and Slack, one might have my browser with all the tabs open that I need, and one is personal mail and iMessage. This was possible on my 11" iPad Pro too, but because I couldn't run full blown apps side by side, the screen size was prohibitive. Not nearly as big of an issue on the 12.9".
I don't like using my personal devices for work, so I don't do this super often, but it's nice to be able to when I need to. And then when the work day is done, I can pop it off the Magic Keyboard and use it for fun stuff or personal projects. After 10 years of the iPad's existence, I am still getting this renewed sense of amazement about how I just used this device all day long for my job, and now that the work day is over I can go into full iPad mode and use it like a completely different kind of device.
I know Windows convertibles have been doing this for years, but in my personal opinion it has never been as elegant or sleek as what Apple is doing with the iPad and iPadOS. I'm sure some Windows fans will troll me for that statement, but I have long thought the slow and steady approach Apple is taking with the iPad and iPad Pro would turn out to be the right one, and I feel like that's finally coming to fruition now.
