some initial complaints
1) Both battery cover and microSD slot covers are not connected to the camera... once it comes off (and the sd cover is tiny) you better put it in a safe place so you don't lose it).
2) The "wide" view isn't as fish-eye reducing as it claims to be, but with some tuning/photo cropping it can be reduced and you can get some really great pictures/videos. Not a big surprise, really.
positives
1) the 48 fps is good... not outstanding, but it's good and noticeably an improvement/cool to have if you want different video types. Looks great on my HD tv and kinda funky
2) the menu system is quick and easy to use, just uses some images to tell you what it is you're selecting
3) camera is sleek and the audio is clean, video capture is great on a Class 10 card... no major lags or stutters in 30 fps and 60 fps is pretty clean.
4) for a camera with no flash, this takes great 11mp pictures (silver version), with no blur in a free hand picture in regular bulb light conditions.
5) the auto white balance is quick, very hard to notice it making changes while the camera is recording.
6) countdown timer to let you know how much recording time/pictures are available based on the current settings.
I haven't had a chance to try out the wifi part yet. I'm taking out to a shinny game this Saturday and will see how it goes/post some fast moving samples. I haven't tried out pro tune mode yet either.
So far, a noticeable improvement on the Go Pro 1 (hardware) and 2 (design) with some added bonus features. Looking forward to seeing it on-track.
edit: looks like bestbuy removed the $329.99 boxing day bundle from the website. ask for it in person if you're getting the silver.
