As a music player, this isn't bad. The touch screen controls are easy to navigate and iTunes works in the usual way for adding music or playlists. The outer is nicely made in brushed aluminum, with an integrated belt clip. For on-the-go usage the touch screen interface is very easy indeed.
However, the FM radio is a damp squib in the rural area where I live and work: it's technically there, but the reception is so poor is might as well not be.
One of the features of this generation of iPods is that it CAN also double as a watch - but this IMO is not one of the better features. The iPod is generally so battery hungry that it's suboptimal as a watch, and although it's small as an iPod as a watch face it's HUGE and cumbersome...
Furthermore wristwatch implementations are very dependent on third party support. To date available watch conversion wristbands generally seem to be unisex and erring on the larger side.
The sports features are a good thing - but also require additional support: in the form of a Nike plus sensor and either Nike plus shoes or a third party converter.
Nearly 2 years after the release of this style of nano the range of cases available is still very limited - most seen to consist of basic frames that wrap around the aluminium housing, but do nothing to protect the screen. The best I've been able to do is a film-style screen protector.
It all seems to add up to a nice enough (though pricey) music player which is capable of a good bit more if you're willing to pay for the added features.
I bought this thinking it would be the best model for workout usage - but don't find it a significant improvement on previous generations of Nano. As a day-to-day player I regret the absence of video features, the continuing need for third-party support and the small interface. It's nice enough but probably not the iPod I'd be aiming to buy next time.
