i spend my entire workday in front of my computer so naturally i need something more comfortable than the stock keyboard that be give to I by my empolyer . i use a natural pro at home and be very happy with it . the natural multimedia have a similar look , but feel very different . the keystroke be a lot smoother , almost feel spongy . the extra multimedia button on the top ... i do not use they . oh yeah , and the keyboard be noticibly heavier and take up more space than a stock keyboard ... there be two main thing that really annoy I : the function key -lrb- f1-f12 -rrb- have be replace by m$ with shortcut for thing like help , undo , redo , open , close , reply , fwd , send , spell , save , print . you can still use the f-key , but you have to press the flock button first . annoy . also , there be a oversized delete button -- it sit where the insert button and a normal size delete button sit .
