I ordered a Kodak Zx1, hope the results will be as good as yours... !
From what I tell specs wise the Zx1 is near enough to that of the Zi8.
Main differences Zi8 does up to 1080p @ 30fps wheres the Zx1 only does up to 720p @ 60fps
Zi8 has image stabilisation where the Zx1 doesn't
Zoom wise the Zi8 does x4 Zx1 does x2
Zi8 has macro focus, missing from the Zx1
Zx1 has the rugged splash proof exterior where the Zi8 doesn't.
As you see not huge differences really.....I use my Zi8 in 720p 60fps all the time, I find the 1080p 30fps mode doesn't really cut the mustard in the end. So really I might as well have the Zx1
Both are good little cams, as I say the Zi8 does what I want without spending the big bucks!
BTW Just make sure you get the fastest SDHC card that you can get....it does make a difference.
