Some great answers there - many thanks. It`s obviously a subject more of us will be assessing. From some of the responses I can tell that it is also the level of awareness people have about the apps. There are a couple out now which are further improved [voice cues, more functionality, etc.]which people may not be aware of and some of the comments reflected that they weren`t aware of the latest ones. It does seem though that at the moment the practicalities of the phone on a run are a hinderance, battery life and concerns about it`s water resilience. Also the GPS may not be as accurate. It`s just that the price discrepancy is so huge, people buying for the first time are bound to try an app to see how well they get along with it. Having said that, what is the point of busting a gut to improve your 10k time by 20 or 30 seconds if the device measures inaccurately? I actually have route I do which I have a pretty good idea how far it is but I do know if I get around 10 seconds quicker then I have a new PB and it`s distance doesn`t matter. Pacing is useful there though. Still interested in thoughts. Thanks.
I have seen reviews where people use various apps on their IPhone or Android phones to measure and log speed, distance and pace. Are these making GPS watches less popular? Yes, you have to take your phone with you, strapped to your arm probably. Yes it`s not moisture proof [sweat and rain]but cases are available. But it`s certainly a lot cheaper to get an app.
I think over the ear are larger but there are also advantages - more comfortable and don`t have the fit problem of when the in ear style gets sweaty they can become loose and even pop out. Have a look at reviews. There are many people who suffer from this. The new "geco" grips still have this issue on their new model. Also the whole bluetooth link idea has limitations. I don`t want to take my bulky expensive Iphone on a run or certainly circuit training. Also music navigation is better with the FX-SPORT and with the swimming and other functionality, for me they offer a lot more. I think self contained is the future and not relying on another piece of hardware.
If in ear is for you have a look also at the Phillips sweatproof version. Jaybird have made a shambles of their customer service with their new model and I have seen reviews saying they haven`t honoured this lifetime warranty for sweat.
These FX-SPORT waterproof/sweatproof bluetooth headphones look completely new on the market and seem to offer stuff I haven`t seen before. http://www.fx-sport.net
The 4GB mp3 is built in like the Sony, but they also have a bluetooth connection for your phone [ to stream music from or take a call] like the Jaybird, but are COMPLETELY waterproof so you can even swim with them. They have a "VR1"model which seems to have a text to voice personal trainer and "race a virtual athlete functionality". This would be quite a package. For me I could have my whole fartlek session mapped out with audible cues [my words] to kick in over the music at designated times, rather like an audible stopwatch and trainer. I could also use it for my gym sessions. This has got to be worth a look.
I have had some inside info that there is a product coming out at the end of 2010/start of 2011 which will not just be better than the Micoach or the Nike+, it will be a lot better. Has completely new functionality. http://www.mi-sport.net It`s not on their site at the moment but I am waiting for this bad boy.
