David Pogue reviews the Sanyo Xacti HD1 for the NYTimes. Registration required and it will not stay up for very long, so read it quickly!
The HD1 is a solid-state (flash memory card) 720p camcorder that will retail around $800. Battery life is only an hour, a 2-giga SD card only holds 28 minutes at max quality, and Pogue makes it seem that there are considerable tradeoffs in terms of image quality as well. Well, it's a version 1.0. We can all hope that the Xacti HD2 will fix all the bugs of its predecessor.
It's a version 1.0 in one sense.
But it's not the first in Sanyo's Xacti line. They have made at least 3 cams in a similar vein before.
Their line of little SD memory chip camcorders is very nice. Standard def is much less critical of poor focus or motion artifacting. I think making it HD was a bad decision. Well, maybe it'll get fixed in the next revision.
