experienced users can write at 39 words per minute.
Considering that the best result on dc's typing contest (i just named it like that
) was f0dder's:
439 keys per minute ~ 87 words per minute.
Dasher doesn't seem that fast.
But it's quite acceptable, and I've read some of the comments on the site, and there are lots of handicapped people saying thanks!
And for those that are not handicapped, it provides a great deal of fun, because the interface is simply brilliant and seems like a video game, and some rest from the usual keyboard typing.
