So far everything has been ok, with SnapChick releasing videos (about) every week. Below is some of her videos. Current videos include the unboxing, hardware close look, setup, etc. SnapChick also has released a video review, with 2 more videos on the way according to a reply to my initial tweet asking about any more videos.
(spaces to make sure videos embed properly)
In this video, SnapChick unboxes the Gazelle, as well gives initial impressions on it (sort of).
In this video, SnapChick sets up her Gazelle Professional.
In this video, SnapChick goes into detail (but not too much detail) about the hardware in the Gazelle.
In this video, SnapChick gives a "review" of the Gazelle Professional, and explains why she would recommend the Gazelle to other photographers.
In this video, SnapChick goes over parts of the Unity interface, talks about the software she is going to install, etc. Go here for more information. I personally recommend you full screen this video if you can, because this video was screen recorded from a 1080p resolution.
So for now, that is all of the videos. Like I said, she did say 2 more was coming out, so I'll (and probably the rest of the Ubuntu community) be looking forward to it.
Update: They are here.
SnapChick uses GIMP on Ubuntu
