This is something that puzzled me for a long time in mobile device reviews - metal (or glass) anything always = "premium", plastic or other synthetic always "cheap", regardless of ergonomics or efficiency. A mobile phone with a grippy back is "cheap", while an an all-glass one that the reviewer might concede is a nightmare to hold and a drop magnet is "premium".

The Forma and the Oasis are both out of my budget, but for me, one of the biggest "wins" for the Forma over the Oasis when I was looking for a new reader was the soft, grippy material. Especially after reading so many complaints about how hard to hold and icy cold the "premium" Oasis was, on its own Amazon.com review pages
