Well I have been carrying and using this one almosty exclusively since I got it and I have a few thoughts. Not a full review yet, but some thoughts.
The main blade is nice. It won't work for lefties and it feels a little loose, but it works quite well and the blade kind of reminds me of an Endura blade. Pretty slick for a multitool. And, the handle doesn't seem too big or bulky when using the knife. Oh yeah, and I did have cause to use it while I was wearing gloves, and no problem at all opening it.
The smaller tools inside work well and lock up solidly. There's some rust on the tines of the phillips screwdriver, but I believe that's the result of using it on rusty screws, not the tool itself rusting. I'm not thrilled that it's as limited as it is, and I would rather have a bit driver than the phillips, but that seems to be splitting hairs.
The pliers work well. They are comfortable to use and the compound leverage operates smoother than some SOG models.
The toothpick and tweezers are ok, but I think I am spoiled by the perfectly flush mounted Vic and Wenger T&T, and while the SOG ones aren't bad, they aren't nearly as smooth as the Vic and Wenger ones. Again, this is a pre production model, and there may be some finishing work being done before these go out, so don't let the details bug you too much.
Overall I like the PowerDuo. The name makes it sound like it should be on Adam West's Bat Belt, and it is more in the class of the Skeletool/Octane as far as functions go, although it's size puts it against larger tools. SOG has a habit of making bulky tools, so I'm not certain if this is a drawback or tradition, but so far the PowerDuo hasn't failed in any tasks I've put it against.
That doesn't make it special, that makes it a good tool, which also covers about 90% of the tools we talk about here. I like it though, and it's a tool I would consider a serious contender for urban type EDC- assuming you are a sheath guy.
Speaking which, I like the sheath. It has a plastic clip that allows to to put it on or take it off very easily, or if you aren't a belt wearer you can clip it on your waistband or backpack strap, Maxpedition bag or anywhere else ou may want to clip it. This is a largely underrated feature in modern multitools in my mind, and is one of the major reasons my father is now inseperable with his PowerAssist.
