iOs & iOs Apps (inc iPhone, iPad, iPod, iBrick)

Good point andy.

I've been very tempted by gps and have done some research you can get a garmin etrex vista hcx for about £150, or the legend for £130, no altimeter, (very popular with cyclist by all my internet searching), "acquire" some maps and you are good to go. Seems like a better and more robust (waterproof bike mount, decent battery life e.t.c) solution.

Ideally I'd like a Garmin Edge 705 but that's quite pricey. I'm just thinking the iPhone app would work well as an interim solution instead of buying a cheaper GPS.
