I'm a programmer not a writer so i often have little need to type quickly. The main gripes I have for this keyboard is Programability (Fn key chording) and separate arrow keys and the weird Control button being pushed up into the caps lock button (sounds like if I ever got used to this keyboard it would be hell typing with anything else).
Minor things to note that I would prefer are clicky version I like my audible feedback of my blue cherrys. And that the keyboard comes in american format only so the left shift bar is long where I prefer the european short left Shift. Doesn't come in duotone which looked cool when someone did it.
Otherwise discounting these minors, I will probably save up for one, it will cost a fortune £200 O_O which is crazy money. The main plus point of the keyboard is its small form factor, silent tactile (useful when you need to keep quiet), style (oozes the cool factor), USB hub, compatibility between mac os x and windows, blank key caps (need to properly learn to touch type by not looking at the keyboard 100% instead of 80% of the time).
I think if Fujitsu made a programmable version of this keyboard with cherry blues or clicky capacitors and dedicated arrow keys it would be a much more buyable keyboard for me. Currently the macbook style of arrow keys suits me fine and would fit right under the right shift, but the main difficulty being whether you could fit capcitor switches in such a short keys. Also like the macbook being able to assign page up and page down to up and down with arrow keys seem preferable. and also have a second Fn key like the lite.
