It’s getting harder and harder to determine what kind of device to buy. A couple of years ago you would have a desktop and/or a laptop. Then netbooks were introduced. Ultrabooks. (Usable) tablets. Hybrids. But a lot of those devices only partially replace this original machine.
A picture is worth more than a thousand words in this case. Especially if there are actually words on it 😉
This diagram is a bit opinionated, does not take into account all devices available and is mostly my personal view of how the spectrum looks right now. It’s how I ended up replacing my Medion Akoya E1210 with a Surface pro 2.
