I bought a Mecam X through Touch of Modern a few months ago, it's got good quality (I used it to record my Halloween fireworks display) and the WiFi is good when it works - the range seems to be a bit limited but because I was doing "set and forget" I just started recording and didn't worry about controlling the camera.
It came with a wrist control which I suppose could be useful, but I have a hard enough time wearing a wristwatch so having a rubbery band on my wrist isn't something I'm going to do if I can help it.
I haven't been able to get it to mount to desktop on my Macs, so when I need to access the video files I remove the card and use a reader. I have no idea if it will be recognized in Windows.
