Query: POOR KEY TOUCH AND BAD LAYOUT.

I owned this keyboard only for 2 days. Since new model has different key layout (short left shift key), it was difficult to capitalize. The other critical part was very poor touch of Enter keys; I needed to stroke just in the middle of keys. This was exchanged to Logitech Wave which has very good layout and touch.Logitech Cordless Desktop Wave Set
