its only a minor update, likely nothing you'll actually need, best thing you can do is just stay as you are for now, and worry about it when a full new rom is released. Also so long as you remove cwr from the phone/restore back to factory settings before running the update you should be fine.
I don't know about you but 10b had terrible video quality for me, shooting in 1080p looked more like 800x480 shot badly, then upscaled badly. That over-processed painted look to the image, terrible.
Now on 10d, shooting 1080p looks a lot more like I expect it to look. Its no Samsung Galaxy S2 for sure, but its decent. Photos still look like utter crap though which is odd, its like whatever fix they did applied to video only as now I think video is actually a sharper image than photos, which makes no sense at all.
