Imagine having a desktop setup and an "empty" laptop case with slide in dock.
Everything in one place. Same system for the iPad.
Will probably never happen though because that's less products to sell?

makes sense when these devices are already more powerful (and expensive) than you Raspberry Pi.
1. No one used Windows Phone either
2. The use-case wasn't really clear.
"Run Office apps on a regular computer-sized monitor!" I can already do that, using the computer-sized computer connected to my computer-sized monitor.
"Setup is simple using Continuum-compatible accessories" So I have to buy a new keyboard/mouse/monitor/something else? (No, but it sounds like I might have to)
The pitch was "You can use your phone kind of like a PC, assuming every app you need runs on Windows phone" (which, for almost everyone, is absolutely not the case). If there's one thing Windows phone was famous for, it was not having apps.
Essentially, Microsoft was trying to pitch you a feature that let you use a phone + monitor and keyboard as a replacement for some of the apps on your PC. Not a compelling pitch, except for presentations.
Circa 1998-1999 I was using a mobile device with a touchscreen and wireless broadband to surf the web and send email while sitting outside. Clearly the idea was good even if Handspring and Ricochet never managed to deliver it with few enough compromises to see mainstream success.
