I have use this design for 8 year . in 2011 , it just stoppp work on its own . do not know why . but , hey , 8 year be fine . I feel lucky to find it still in production . I do of course shop around at Staples , etc. to see what I be miss . what be new ? - rediculously expensive and oddly shaped keyboard that be package with a mouse I do not want . you can not improve much on perfection and this m keyboard be already the perfect shape . so , I save a ton of money and buy exactly what I need - a keyboard that do not fatigue my finger . I also like it be white so I can see the key when it be dark in the room .
