Smartphone apps for tracking rides

[saltwag]

Do any of you use a smartphone app (or dedicated GPS unit) to track your rides? What's your first choice? I use Endomondo and it's pretty sweet, giving ride info such as:

Start Time
Sep 24, 2011 3:51 PM
Distance
26.12 km
Duration
2h:16m:51s
Avg Speed
11.5 km/h
Max Speed
55.5 km/h
Calories
1223 kcal
Altitude
1130 m / 1346 m
Elevation
504 m ↑ / 563 m ↓

It uploads each ride to www.endomondo.com (and Facebook if you want) once you've completed it, and you can share the link with anyone. Great for future reference and being able to see on a map exactly where you went! For example I went riding in Hogsback this past weekend - here's the link: www.endomondo.com/workouts/23675321

On a smartphone - I like endomondo, easy and free.

Also use it - it's great, but elevation is an approximate... my house either gains or loses a good few netted above sea level each time I ride! Also, I've noticed a big difference btwn HRM calculations of energy used and endomondos. Does this mean I'm fitter then endomondo thinks?? It's a really fun way to track your rides though. There's also an option to link with a Bluetooth HR transmitter belt. Anyone used this?
