I suggest you to look at this post I did few weeks back. It discusses the upgrade from T6 to T6c. Including what is new and what is lost after the upgrade.

Becoming triathlete: Should you update T6 to T6c firmware?

	Suunto t6 - Click for more info The Suunto t6 is one of the most exciting new personal training devices to hit the health and fitness market this year. The "t" in t6 (if you don't want to get too technical) stands for "training". It actually refers to the time interval between two heartbeats, or EPOC. Measured to the millisecond, this interval allows you (using the included PC software) to assess your current fitness, set a proper training load, measure your actual fitness gain over time, and achieve your overall fitness goals.
