Not for the kinds of things I still need a Mac for.
But YOU aren't doing the types of work and projects I still need a Mac to do.
You're the one who wants to do away with a full blown Mac and downside/minimise/de-clutter your life.
For the digital art I create, I still need the large 27 inch screen size and computing power a full blown computer/Mac affords.
I use my iPad Pro though, exclusively, as a portable digital drawing/painting canvas,sketchbook, ideation book/creation and writing journal book.
I, also, consume various online video content and online image content in the form of an image scrapbook-like device.
But I am NOT going to give up using my Mac.
iPads are not on the same computing level, as yet.
If you want to simplify your computing experiencd and use an iPad, exclusively, you should purchase a newer, larger storage iPad to be able to more “approximate” as close to a laptop-like experience, as possible for this device.
Plenty of iOS Apps in the iOS App Store for just about anything you want to do or try to do on an iPad.
You just need to understand that iPads, ANY iPads, are downgrades from a laptop/MacBook
Have you given any consideration to looking at Microsoft Surface tablets?
These are more expensive, but DO a lot of what the iPad can't do.
Microsoft Surface tablets are a full blown laptop replacement.
These combine a touchscreen tablet with a full blown windows OS laptop experience!
These are around the same size as iPads, come standard with the Surface Pen, can use all input peripherals like keyboards, trackpads or mice and have lots of connectivity ports.
The Microsoft Surface tablets are just as light and portable.
Something to consider, as well!
