Nspire CX class were powerful enough to run quite a lot of GBA games. And I think the Ti-84 is probably still kicking around because no one really wants to bother buying more overpriced calculators that work just fine. The Z80 TIs are quite interesting in their own right, but a good majority of people are probably bored just thinking about such a device. Same thing with the Z80 based Rabbit 2000/3000/4000.
