MiniDisc PLayer

What is the actual difference between the sony mz-n710 and the sony mz-n810 apart from £70 and a radio?

I asked in Dixons. My words? “What am I paying the extra seventy quid for? a radio?”
Salewoman “Yes.”

I find it hard to believe that even sony could be that cheeky. While we’re at it, IYHO would I be wasting mony on the 810? I want a minidisc with a radio dammit and that is the only one around.
