I was doing a yacht delivery last week (Largs in Scotland down to Cork in the South of Ireland). At one point our GPS started playing up and as we were in 200m visibility, taking a bearing for a fix was a no-no. Now we knew where we were an hour previous, but DR (Dead Reckoning) is only so good when there are lots of rocks around.

Fire up the NiT, get a fix - oh and while I was at it noticed there was just enough phone signal to pick up a synoptic chart and the latest shipping forecast while I was at it.

Where am I going with this? Well, with regard to the OP, I don't care if the engine is a Mustang, it stil potentially saved my life by allowing me to position myself in limited visibility.

Regarding the iPOD Touch/iPhone vs NiT, well even though one of the other crewmembers had an iPhone, on the same provider (O2-UK) they couldn't get a signal, and as it wasn't the new 3G iPhone they couldn't get a fix either.

/sets fanboy mode off for a moment.

There's no denying the visual appeal of the UI on the Apple candy-bars. It's smooth, intuitive and well thought-out; perhaps there is a proportion of the NiT userbase that would like something similar. But there is no comparison between the two when it comes to customisability and all-purpose capability.

Horses for courses, I suppose.
