I'm most excited about the video recording (720p) because it allows me to always have a way to get my 20 month old son on video no matter where we are, and also record my wife as we're expecting our second (see this is why I need to win it free, cause the kids drain the $$). Then with the HDMI out, it allows me to share that on our HDTV or quicky upload to Youtube to share with family over WiMAX (coming soon to DC area) .
I'm excited to have a device, in every day use, that will replace our camera, GPS, 6 year old tablet pc, and 4 year old SD camcorder.
The records we'll be able to keep of our kid is just fantastic.
