The "saving paper" aspect is so great, especially with the advent of the Pencil. We still get a lot of forms emailed to us from our kids' schools and little league teams asking to fill it out and return via email or on paper at school. Instead of doing any printing or scanning of any kind, I just mark it up right from the email attachment and email it right back. When I'm using Affinity Designer and need to sketch something out to get an idea of what I want to do, I sketch it out in Procreate first and import the sketch if needed instead of printing, scanning, and then importing.Agreed. I'm a network admin, do most of my heavy lifting with my Surface Pro, but I use my base model iPad every single day. I use it as my computer at home (pay bills order online, etc), I even VPN into my office with it and use Remote Desktop, use Word, Excel, iCloud for my files, text, surf the web, email, music streaming, watching a movie or TV and so on. Not one time has this thing slowed down. It is the first device I pick up in the morning when getting my kid ready for school because she wants to know what the lunch menu will be that day (I like to save paper so the schools menu, in PDF, is easily saved and accessed on my iPad). It is a fantastic little device, and when iPad OS becomes mainstream, pair it with a mouse and keyboard and you have a mini computer (with a quad core processor) that runs iOS/iPad OS blazingly fast.
I've actually been using my iPad as my main computer for years--it's been my preferred computing device ever since the iPad 2 in 2011. My employer gives me a new Mac every few years, and I will happily do my 9-5 job on their equipment instead of putting wear and tear on my own, but I would not replace it or miss it if they took it away. I'd just stick with my iPad Pro.
