PPC Phone or SmartPhone?

[kuph]

It's my understanding that the difference between those 2 WM5 categories is that PPC Phones use a stylus and Smartphones have no touch screen.

Unfortunately various websites and writers play fast and loose with those terms. I've seen the Treo 700wx referred to as a Smartphone, but understand that it is a typical stylus product.

I have seen both the Motorola Q and the new T-Mobile Dash referred to as Smartphones. Handango lists the Q as a Smartphone and does not mention the Dash yet.

The software I want to use is not listed as working on true Smartphones (Epocrates and Leonard Maltin's Movie List) but runs on PPCs and PPCPhones. I like the looks of the Dash and have seen it referred to as a PPC, but isn't it like the Q...no stylus?
