I just wrote something in another thread that fits perfectly in this thread: a lot of what I wrote mirrors what others have included here: access to multiple/bigger displays; better file management; better e-mail tools,
I really like using my Mac; always have. My 2015 MacBook Pro (15”) is the best machine I’ve ever owned. But for reasons I cannot explain, I’d really love to be able to work 100% from my iPad — without decreasing my productivity and without using underpowered tools. In fact, I don’t want it to replace my current tools, I want it to improve them in every way. I would like to have better tools, more efficient and productive work flows, better automation, and the like.
The iPad already has for some things—reading an annotating documents, which makes up a huge aspect of my daily work. It is the undisputed king of note taking. I have others, but those are big ones. Research is excellent on an iPad. File access is fine (but file management and batch processing is a sore point). A lot of database tools are excellent.
I like iPad multitasking but think there are some things that could make it at least as efficient as multitasking on a desktop-class computer. You don’t need to have arbitrary windowing to solve the problem of needing access to multiple tools and channels of information.
An iPad will never be a Cray supercomputer. But it should be able to enable a professional to do everything a professional can do on “any old computer.”
