P900 language teacher system -- what does it do?

Hi,

I'm intrigued by the P900 series, but the description on ectaco.com --

"Patented Language Teacher system with hands-free, eyes-free U-Learn™ Car Tutor"

tells me pretty much nothing. What IS the Language Teacher system? Are there grammar lesson's, etc., or is it just vocabulary cards? What is U-Learn? How extensive are the U-Learn lessons?

Thanks for any help you can provide.

Dear Sir / Madam,

The Language Teacher system will pronounce words, phrases and dialogs for you. It will show you a word written in a foreign language, show you translation in English, show you visual image of this word, pronounce it for you in a foreign language, evaluate your pronunciation and offer you a test to make sure you do it correctly.

This unique system gradually builds up your vocabulary and pronunciation through lessons and quizzes you can take at your own pace. It even shows the percentage of how many lessons you have completed and how well you're doing.

The U-Learn™ Car Tutor lets you use the Language Teacher system hands-free and eyes-free while driving a car.

Please let me know if you have any questions.
