You know, every time I hear this nonsense, it makes me laugh. Let's translate what you said into fact.
People use computational devices to accomplish something. My iPad mini 4 was more powerful than the Cray super computer in Sneakers. Then I traded it in on an iPad Pro that was twice that powerful.
My iPad Pro is about as powerful as an i5 from 2013. It can handle all the tasks I throw at it. Why do I know that? I'm an information security engineer by day, and college student at night. I work from my iPad. I create all my assignments, on my iPad. The docs I create for work, from my iPad. The "connection and manipulating components on the network...." From the iPad. And I don't use MS software either. Pages, Numbers, Keynote...
So I do REAL work everyday on my iPad. Because it has LTE built in, I can do it without a WiFi network. So when I'm on call, I don't have to panic if I am out doing things...
I tell you what, let's you and I do my job for 8 hours straight. You get a Surface 4, and I get my iPad Pro. Let's see how great things are going at the 3.5 hour mark? I bet you can't do ANY work, much less REAL work, without being plugged in.
You see, DOING work, is about being able to actually DO work, something that can't be done on a Surface from hour 4 on, in an 8 hour day.
So while you work part time, I'll cover you full time with my "toy."
