What is all this about MP3 USB Keys ?

Hello,

Can some-one please tell me :

What is "Organic EL screen" ?

I am new to MP3 players.
I want to buy one that does not only play mp3 files but also play and record the radio aswell as record voice/sound/dictation.

Anyway, I am not interested in the "flash memory" ones because even though they are "remove-able memory" they do not contain that much space. And, those that do are too expensive.
And so, I thought it would be best if I get the one that has "internal memory" (hard drive) that can hold music aswell as data files so I can easily transfer important data files from my pc to it and carry it on my pocket always.

Anyway, as I was shopping around, I came across :

MP3 USB Key, Internal Memory and Hard Drive (3 types of MP3 Players/Recorders). Now, I am spoilt for choice. I mean, what's the difference between the "Internal Memory" type and the "Hard drive" and the "MP3 USB Key" type MP3 Players/Recorders ?
And, if the "MP3 USB Key" type is a "remove-able memory" then why do the following links advertising "MP3 USB Key" Mp3 Players/Recorders technical information section mention that they do not have "removeable memory" ?
Strange !
I am going to ask the website these questions but usually it takes 3 days for a website to get back and I can't afford to wait that long as I need to buy one immediately and so I need your brilliant helps.

Anyway, after checking a lot of brands and models I have come across many technical words that I don't understand. I have listed them in BOLD below so please try to explain them to me as much as you can.
I am not expecting anyone to explain every single technical words which I have listed but if anyone does volunteer to do so then GREAT !!!
I am not just simply listing the technical words because if I do that then maybe you too won't understand as some-times different websites list different words (which you have never heard or read before) explaining the same thing. And that is why I have listed the "context" aswell as the links so you can check the "technical information" of each MP3 Player/Recorder on the links yourself to check-out the full contexts of each products's technical descriptions.
Please note that I am not spamming the links because I don't own them and I am not affiliated with them either otherwise I would have listed my referral links.
Please look-out for the BOLD text for those are the words which I do not understand and need help to understand them and look-out for underlined text because those are my questions.

Thank You
