> One of the earliest HTC android devices, after the Evo 4G, was a version with a slide out keyboard.
The first Android phone (let alone the first HTC Android) was the HTC Dream, with a physical keyboard. Back in those days Android didn't even have a software keyboard -- you had to use the physical keyboard.
By the time the Evo 4g came out, hardware keyboards were already considered second class citizens. The Evo Shift 4g had a worse screen, worse camera, and a worse CPU than the Evo 4g despite being released a year later.
Thankfully a few companies have picked up the UMPC market, with products like the GPD Win and the Gemini PDA. I don't need a hardware keyboard on my phone, but I do need a portable device with one for emergency SSH sessions while on the road.
