Yeah, I'm counting phones and tablets as two categories. But I'm also being really generous on how old something can be and still be "new" (15 years is quite a while, in tech) and not counting those as just an iteration (admittedly, a big one) on PalmOS devices and such. They're also much closer to being general-purpose devices than most other appliance-type machines (consoles, dedicated set-top boxes, et c.), occupying more of a middle ground between the two.
I suppose you could add smart watches and make it three. Set-top boxes are at least 23 years old (TiVo), so stretch even generous definitions of "new", and we had closed-source non-user-modifiable DVD players well before that.
