Sorry but if your assumption that CMOS sensors were superior over CCD is true then canon should have used CMOS sensors on their compact digital cameras like powershots and IXUSes as well. Canon DSLRs have choosen to use cmos because they are well performers when they are very large since light sensitivity is adequate enough to render the colors and details suitable for DSLR-quality images while at the same time reduces power consumption. in other words CMOS sensors are well performing enough when large but are still mediocre to CCDs when shrunked to fit a compact digtal camera especially mobile phones.
Anyway may i remind those who claim CMOS are better/par to CCDs that where and when have you seen a cmos digicam(i said digicam not DSLR cam)/camera phone being able to beat/par a CCD enabled digicam/camphone with the same sensor size, similar lens, and same resolution?

@razec
Are you really serious? Your statement is true maybe few years ago during CMOS infancy. But now it's a fact that CMOS has now surpassed CCD in almost all respect.
Camphones today don't perform well because they use inferior or older CMOS sensors... Marketing, cost & product positioning are also factors... but that may change 2morow..

Agree to that 100%.
but what i want on my camphone is
1/2.5" 2MP CMOS sensor.

Far exceeded??? How far???
Claimed??? or Proven???
Faster... Ok, but how much... Energy efficient... Ok, but how much... Cheaper... Ok, but how much... Wait a minute, why use CCD in low-mid if they are costlier???
Also, what about picture quality and noise levels, especially at night/low light (I am not talking about DSLR's)???
