The DNA's camera is smoking fast.
One thing you do need to do is hold it steady when doing continuous shooting.
My mother in law had her stand alone digital camera at Christmas and while she as missing the smiles and all the good shots I was shooting dozens of photos every second and got far better shots.
Granted it drops to 5mp when on continuous shooting. But having a good shot is what counts.
And even when just taking repeated 8mp shots, it is fast. More than one per second.
HTC put some decent power into their dedicated imaging chip.
Upgrading software is one thing, but having the hardware is more important.
And I think the stock camera software is pretty good.
