The wireless phone that has one, it's an interesting concept but apart from this detail not necessarily very important (haha), when modifying a picture with Photoshop, it would be nice 1. avoid writing anything on the sensible window having the number display, there it has 9 digits and is therefore invalid; 2. Why change the keyboard and remove the "6" to replace it with a "9"? It will be difficult to type eh numbers.
