A friend of mine got a Stone edge stem for testing a couple of weeks back. These things looks impressive. 7075, fairly light and pretty damn good looking. The 70mm weight more than a Thomson, but the 50mm matches Thomsons weight.
The Stone Edge stem above uses an almost identical clamping system to the prototype e.thirteen stems that we have been testing since late summer last year and it has been working great. Thomson doesnt have to worry about the majority of its users smashing their knees on bolts, a big factor IMO. At least its big for me! I have one of the new Thomson stems and its nice.

If you read the reviews on MTBR, almost all of the negative reviews are because the users claim that the stem slips. Which is entirely an install problem - installed correctly, I've whacked my bars pretty hard and not had the thing move a millimeter.
The Thomson clamping mechanism is definitly more finicky than a standard setup when installing it, but if you just spend more than 15 seconds torquing down the bolts, there are no problems. The problem is most people don't read the setup instructions, and think torque wrenches are for wimps, so they tighten one side until it "feels tight", then torque down the other side, and call it a day.
