The new Canon Vixia HF S11 comes with 64GB of internal memory and a SDHC slot to record 24 hours of video. An entire day of my life? Record every single shower, brunch, and embarrassing moment? I'm so there.
Granted, you will need Batman's utility belt full of extra batteries, but it's completely worth it. The $1,400 camera uses a 8.59 Full HD CMOS image sensor, coupled with Canon's Digic DV III image processor, which means that apart from the 24p cinema mode and 30p progressive mode in Full HD, you will get 8.0 megapixel photos. It also has manual gain control limits and manual focus.
The camera comes with other new features, like a new stabilizer technology—called Dynamic SuperRange OIS system—that works while you zoom in and out, and a new Advanced Video Snapshot Mode, which records "a series of four second clips when in shooting mode." I don't know exactly how that will work, but I'm sure family and friends will be glad they won't have to endure 24 continuous hours of panning through mountainous landscapes and European ruins.
