But you know you want to order one... go ahead, we won't tell.
It's a nice unit; mine (HR + cadence) arrived while I was out of town this week, and I set it up tonight. After charging it for a few hours I turned it on while sitting on my couch (at least 20 feet from a window) and it got a weak lock on 6 satellites, and it's location error bounds were under 30 feet (this is as good or better than my Garmin 76C gets outdoors). It comes with mounts for 2 bikes, and the mounts can be rotated 90 degrees so that the unit can be mounted on either the stem, handlebars, or aerobars.
The batteries in the cadence unit were installed backwards (I've seen this reported a few other times on the Garmin Yahoo email list). Rumor has it this is intentional, in that it saves battery life until the unit is attached.
Still a few bugs in the death ray, though. Some are mistakenly aimed to the rear and vaporize the rider instead of the competition in front
