After a couple of days:
I am a slow but reasonable '10-finger-touch-typist' in several languages already; having to type new words ONCE would be fine for me; later on I'd only want to re-type difficult words.
But having to type even simple words over and over again becomes EXTREMELY BORING AND COUNTERPRODUCTIVE, and slows down reviews considerably.
Plus, lingvist now treats simple typos as failures, and thus constantly presents cards I already know very well.
Last not least, the level is too low; I already know 80+ % of new words.
