Wrist Cycling Computer

BikeSwan

Hi,

What's the best wrist cycling computer?

I'm looking for a cycling computer but I want one that is wrist attached (like a watch) as opposed to the handlebar mounted units. I mainly cycle but I also run occasionally so it would be great if there was one out there that is mainly cycle orientated or can do cycling functions as well as a normal cycling computer.

Functions i'm looking for:

Speed
Distance
Cadence
Heart Rate
Altitude (not needed, but would be nice)
Temperature (not needed but would be nice)
Some software I can upload data to and view it
Power Unit compatible (Ant+)


I was looking at the:

Polar RS800CX
Polar CS300
Suunto T4D
Suunto T6D
Garmin Forerunner 310XT

Im edging towards the Suunto T6D because it seems to be the easiest to use, and has the most features for the price. If there genuinely is more of a feature advantage by going for a handlebar mounted computer then I will go for one of those but I really want a watch design.
