A while back I switched from a MacBook to a Chromebook as my mobile computer and for the past 4 years I have been using an Asus C302 Touch Flip as my main mobile computer. For the most part I do all my video editing on my iMac in my office but will do some video editing on my Samsung Galaxy Android phone using a program called Action Director which gets the job done but is limited in functionality for sure.
My Asus C302 has been a good mobile computer but I was not using it much for video or photo editing. Way back in the day when the first iPad came out I purchased one but back then all they really did was simply make all the iPhone Apps looks bigger, there was very little added functionality that allowed them to do much more than an iPhone could do. Time has been really good to the iPad lineup allowing it to in many cases even replace a laptop for some people.
I am a bit of a Techy and like giving new technology a try and so after playing around with my mother in law's iPad 7th generation I decided the new iPad software would be able to do everything I needed it do do with only a few work arounds. There are several iPad options out there, the standard iPad, the iPad Air and the iPad Pro with several screen sizes to consider. After some humming and hawing I went with the iPad Pro 11 inch in a 128gb version since most of my video files would be stored on an external drive. I purchased a Logitech keyboard case with built in trackpad and it works awesome making my iPad Pro 11 inch feel just like a laptop. I don't really ever feel the need to add a mouse but I could if I wanted to.
For my video editing software I paid the $35 or so and installed LumaFusion, an amazing full featured pro video editing App that even allows me to edit 4K video on my iPad Pro almost as well if not even better in some ways than my iMac using ScreenFlow. In fact this YouTube video was edited entirely using my iPad Pro with LumaFusion!
