Do you mix them? That's why I'm going to stick with PWs, at least for now - the ability to trigger both my 430EX IIs and my Einstein and control the power of them all from the camera. If Canon comes out with an ST-E3/600EX-RT-compatible RF receiver that has a PC sync port, I'd strongly consider switching. Also, changing power levels with the AC3 seems a lot quicker/easier than the buttons/menus of the ST-E3/600EX-RT.

First impressions of the 600EX-RT - man, that's a big box, almost the size of the box for my 7D! The tri-lingual manual is over a 1/2-inch thick. A very solid, well-built flash. Sticking in some eneloops and pressing the test button, it flashes. That's about it for first impressions.
