I've been playing with it since late winter. It's pretty cool because you can walk up to any computer with internet access, log in and use SketchUp. If you save files to your Trimble Connect account folder, you access them from anywhere, too. It is currently limited but the basic tools are all there. It's mostly a matter of getting used to the user interface. No options for installing extensions yet but that might come down the road. For me it won't replace SketchUp on my desktop or laptop machines but I can see some uses for it.
