Blank Keys to Type up to 100% Faster
Like on a piano, since there are no keys to look at when typing, your brain will quickly adapt and memorize the key positions. Within a few short weeks users increase their typing accuracy and find themselves typing up to 100% faster.
I just can't justify something this indulgent. I'm already a touch typer who rarely looks at the keyboard. Would it really make me faster? I was counting on 8 hours of practice a day to do that.
