I usually only review thing if they make a huge impact on I -lrb- good or bad -rrb- . this keyboard be a truly great product . I 'll start by qualify the con which have already be point out by other : \* Slow wakeup time . if you have not use it in a little while , tap the spacebar and wait a few seconds . that be all . it be really not such a terrible thing . \* dedicate home and end key . this one I agree with , although there be way to re-map you keyboard . this keyboard have dedicate page up\/down key with home\/end as extra function . on my pc I be go to use a keyboard mapping program to reverse the key so that home\/end be the primary key and page up\/down be the function key . for this I give the keyboard 4.75 star instead of a even 5 -lrb- or would if I could -rrb- . now we 'll talk about the good thing : \* size : have the number pad separate from the keyboard be inspire . not only can you carry only one or the other if you so choose , but the unit allow you to make better use of limited space by arrange the two part of the keyboard however be most convenient for you . \* shape : I usually only use the split keyboard -lrb- ergometric -rrb- . on the other hand , there be no deny that a ergometric keyboard take up a good deal more space than a straight keyboard . this product strike the perfect balance : the design offer about 75 % of the ergonomic advantage of a split keyboard while only take up 10 % more space than it would have if this keyboard be completely straight . \* Action : this be very much like a laptop keyboard , which worry I at first . I hate laptop keyboard : I can only ever manage to type half speed on they . for some reason , though , this product give I probably the best typing experience I have ever have on any keyboard , laptop or otherwise . as I type this review , I be amaze at the speed I be achieve , especially consider the next bullet point . \* support : most review be not able to comment on this , but my keyboard arrive with a broken `` e '' key . the key will not stay on and keep pop off while I type -lrb- and yet I can still manage to keep up over 80 word per minute if I be careful -rrb- . I call Microsoft support , get a human be after hold for less than 10 minute , and be tell that a replacement be en route and that I do not have to worry about ship the old one back . needless to say I be very pleased because I love the keyboard .
