As I unpacked it, I was first aware of how small the nano is. If you're used to an iPod Touch first a conversion.
The material feels high quality, and also looks really chic, but the low weight and the extremely thin design, I often feel that the iPod does not really withstand anything and one should better handle him with kid gloves. For me, however, a small flaw: a tiny adhesive residue emblazoned above the screen ...
Once he is in your hand and I play around with it but makes it a very nice impression! Everything is super liquid and because of the ease of use it had to be back on iPod (iPod touch has so far been my favorite player).
What I find disturbing, the lower bass is compared to the Touch 3G, which is why only 4 stars. If now someone thinks "just take better headphones": I've been using for a year the same headphones, which have turned out to be after a long search my favorites. Because it can not be so!
Conclusion: feels upscale, though not very robust. Sound is very good and the price is ok (other MP3 players with 16GB up playing in the same price class).
