I buy two of these on sale from a local retailer . while they be good as a quick replacement keyboard that be also wireless , serious typist or anyone picky may want to look elsewhere . -- pro : the wireless component work pretty well . it can also work with a Panasonic plasma tv , and some of the function key can access important part of the menu . I like the nano-receiver . I can leave it in a laptop , and wrap a sleeve around it . at the very least , the regular function key be the default , instead of force user to press a `` fn '' key just to access `` f2 '' and the like . of course , the blue-labeled function key like volume up or change track do come in handy . -- con : Logitech remove a lot of important modifier key on the right side , notably the Windows key and the context menu key , the latter of which be replace with a blue `` fn '' key . this be a disadvantage for both Windows and Mac user who frequently use keyboard shortcut . -- MISCELLANEOUS : I do not mind the `` dark fleur '' design . the feel of the keyboard , for I at least , do not quite feel substantial . I can get use to it if I be force to use it daily , but without the miss modifier key on the right side , I probably will not use it in the end . it be also kind of big to use for a home theater setup , unless you be do spreadsheet on a big screen tv . it be still fairly lightweight .
