- there be only one CONTROL button . - the CONTROL , ALT , DEL and WINDOWS key be really small - I hardly ever hit they unless I look down at the keyboard . - del be right next to the left-arrow key - so you 'll often hit it when all you want to do be move the cursor leave . - the stupid tilde-backquote key be right between the space bar and alt - senseless . all in all , what I have experience be this - for `` plain '' textual typing , it be fine - all the alphabet key be very usable , as be SHIFT and ENTER . backspace be fine too . but the navigation key be very hard to use . and combine that with the point I list above , it be one big disappointment . it be SO short , unnecessarily so - the maker could easily have add 2-3 inch and make it much more usable . as a chronic rsus sufferer , I want a truncate keyboard that allow I to keep my mouse closer - even a normal keyboard without the numpad section would have be just fine . this keyboard be overkill ; it sacrifice too much useability in try to be smaller . I advise against buy without try . and if you do try it , keep in mind the various kind of typing and application you work with - document , email , programming tool etc. . it be definitely not programmer-friendly .
