MotoX - interesting.
The OnePlusX looks nice but I don't want a Chikom device. isn't it a Chikom device, not just one assembled there?
Looks very Alpha-esque to me with the chamfered metal sides, and shape, but importantly lacks the flat glass front that the Alpha has. That kind of flatness is very nice and looks like the phone has been made from a bar of swiss chocolate. Remarkable when you see it up close - does anyone here have an Alpha? The Alpha followed the SII in design, but with metal edges, similar to the iPhone 4 or the Blackberry 9900s with their metal edges, but it has something to it that makes it look very flat.
I agree that the Sony Z series are very nice, but the glass wont survive a fall and as I said ,they're slippery. If you want to go caseless I'm not sure if they're good for that.
Also the Alpha has a removable back with a "cats ear" like feel. In a fall the back and battery will come out, distributing the kinetic energy from the fall away from the glass and phone itself, and also it has slight bumps on each corner with an increased radio preventing further damage, and alllowing the pone to be sat on its side despite the presence of the buttons.
They say they were inspired by their Cardphone, but it's obvious the Alpha is inspired by the SII. You can see some elements from the Cardphone in the Alpha, such as the chamfered edges, giving it an angular feel to the front. Compare the SII which seems to have, like the S3 S4 and S5, but not as much as them, a slight lip or curved edge up to the front but it's very much like the Alpha. The Alpha has a chamfer and then a completely flat front. I think the Sony's have this as well but the Alpha just looks completely flat.
As you can see the Sonys don't ahve the Alpha flatness, but a type of S3, S4, S5 lip but not the same curve but seems more flat than the Samsungs (even though the Z2 had chamfers). But the Sonys do have much tighter radii on their corners, which is nice. Still the SII and Alpha radii are pleasing for their shape. It's the 100% flatness of the Alpha that's striking when you realize it's a SUPER AMOLED there. So bright and so flat. I suppose the AQUOS has a similar effect when you look at it. It reminds me of being like a thin block of Lindt chocolate in its shape. But the Z series look nice. Take a look at this:
It's this kind of Alpha thoughtful designwork that you can see Samsung putting into the S6 and S7 but again, I'm not sure how they would go if they were dropped compared to say an SII or Alpha.
