These aren’t new but they are interesting in that they focus on what feels and works well. I doubt replicating the quality of the original analogue phones that these phones have as a source of inspiration was their original intent but they are designed to be ergonomic and user friendly. I think products like these are a statement that not all new forms are an improvement.
The Yubz talk online series works without the need for a software install, comes in 4 vivid colors (Jet black, Alpine White, Russian Red, Lemon Yellow) and works with either a PC or a MAC. The focus of the product would be software like Skype but I assume it would work with most voip software.
