If the Pyra was going to look like an iPhone then I might cancel my pre-order.
Steve Jobs was a turtleneck wearing hipster and the iPhone had a dumbed down UI. It's a large slate of glass with big brightly coloured icons on it. That's professional? That's the kind of UI that a toddler would use. The iPhone treats it's userbase as if they're mentally retarded. It's simplified and limited and the only good thing about it's UI is that simple people like toddlers and Steve Jobs admiring hipsters can use it.
And ever since, big phone makers have been trying to copy it across their entire lineup. Samsung had the ultimate 'not an iPhone' in their Galaxy Note line-up through the Galaxy Note 3. It was the ultimate 'nerd phone'. It had a real headphone jack, microSDXC support, a garaged stylus, a (then) giant screen, a user removable / replaceable battery, HDMI support through docking, AND a microUSB port able to roll data at USB 3.0 speeds. Starting with the Note 4, they have progressed to where the Note line is 'just another phone'. Hell, they even made all of the accessories white and made white cased versions of their Note phones with glass backs. I loved my Note 3 - and every Note device they made after it kept compromising the features that actually made it special.
I don't need my device to be razor thin, I need it to have decent battery life. Waterproof can be handy on occasion, but I'd rather be able to use wired headphones and be able to swap the battery out every year or two.
My current device is a Planet Computers Cosmo. No stylus, but the touch type usable physical keyboard makes up for it.
All that said, I don't see the Pyra becoming my regular in-the-pants-pocket device. Everything about the Pyra is great - except how thick it is. The thickness of it is actually a plus for gaming comfort. But - in a front pocket of a pair of pants it looks like you're either smuggling bricks or worse. That said, I don't see any way that the Pyra could be made any thinner and retain all of the ports as we want and like them, let alone the great big battery pack and durability of construction, etc. The device is the size it needs to be in order to house all of the flexible and functional equipment that makes it so wonderful. But, maybe, someday, if the Pyra in current form sells 10,000+ units, maybe a 'Pyrathin' might be able to be made as a thinner device with only microSDXC slots, only USB C ports, etc - which -might- get it down to 2/3 of the current thickness - which might not even be worth the costs of doing it.
