I purchase this new m ergo keyboard with high expectation that it would be better for not as good as the previous generation . but it turn out this be not a very good keyboard . for my personal usage , I use the Windows key a lot for shortcut . especially the `` Windows '' + `` m '' combination where it minimize all the window . to my surprise , there be no `` Windows '' key on the right hand side of keyboard . this be very annoying because instead of be able to minimize all the window with just one hand , now I have to use two hand !!!! some ergo expert in Microsoft be obviously not think . or perhaps someone in m think they be such a ergo expert that they decide to ignore everyone 's complain . the other problem I have with this keyboard be that the `` j '' , `` U '' , `` h '' key sometimes do not work . I would be typing and all of a sudden , none of those letter would come out . I have to hit those key harder to ensure those key work . this be not what I would call ergonomics design . I like the previous generation m ergo keyboard much better .
