Although the question was asked a long time ago, it may now be relevant if the purchase of a new device is planned. I got a total discount of 35% then, and the postage was free - so I paid a total of about $90 which seemed like a very decent discount to me.

A lot has already been written about what X has compared to S, but as we can see with the latest firmware update what X has is quite a large storage, while S has to face user criticism for losing 4kb.

In the long run, the new model has its advantages - but from the perspective of "I don't need Bluetooth, a bigger screen and more storage", the old Nano S is quite a good buy.
