I have a Microsoft Surface, an iPad, and a Samsung Galaxy.
The Surface came first, as a way to replace my ageing iPod, then I started watching Netflix and playing games on it when not near my desktop. Then the iPad, primarily to play BitLife, then we got a Ring doorbell so now I use it to monitor the doorbell as well. The smartphone came along because my old dumb flip phone died; I pretty much only use it to make calls and get a Lyft.
