I watched and desired it for years, too expensive to justify a sudden purchase but way too cool to not remain a latent "monkey".
Once I found it on eBay at 60 euros -everything included- I did not resist.
What can I say: it's even more accurate than I expected. Well, you have to tweak yourself a bit (eg.: raise fingers after "pression", slow down typing rate, check light conditions), but anyway it works really good.
Programmin' with OpenLISP on my Qtek 9090 will be much funnier now!
