Ah, sorry Katie. I can't resist the snarky question. Which is, why? You obviously are very active, so you know very well whether you worked hard or not and what your approximate calorie burn was. And with a basic altimeter watch you certainly know the key metric: how many feet of "up." The rest is eyewash.
The Forerunner 305
But that's me. These days, I'm down-sizing my electronic aids. They don't tell me anything interesting (well, aside from how many vert feet to pass/summit/camp), and I just don't care any more.
Still, I think I know what you need. Garmin's Forerunner 305 ($299). It's a wrist-mounted GPS designed for active people, and it measures distance, calories, vertical distanceall that good stuff. You even can go online and chart your performance, compare training workouts, and so on. If you must.
The 305 also is pretty compact. More of a fat wristwatch. So it works well as a small add-on to your workout.
I think the Suunto X10 is fine. Its compact size, which includes GPS readings, is a big plus. Can't read calories? Well, the Garmin is just guessing, so there's that. Seriously, all you can do there is sort of guess. Why don't people love the Suunto? Same reason nobody is all that wild about any of this stuff. It's just too complicated.
