MOUSE: For years I use on my gray-flecked table countertop Optical Mouse from Logitech, Cherry, Microsoft and no-name manufacturers. No need to date a mouse pad. Whether 1000 or 2000 dpi are set in this mouse, it always comes back to jumps in the cursor display on the screen. That is not ergonomic shaping, you could see at the figure anticipated. Why it but must be 124 grams, me and my wrist remains incomprehensible. KEYBOARD: The defendant also has other unusual arrangement of the INS, POS1, Page Up, Delete, End, Page Down keys with 2 keys in 3 rows instead of 3 keys in 2 rows, also a non-10-finger typists compels to always have to look what you just pressed. As helped also no one-week adjustment period.
