you are comparing a US$500 camera with a US$1500 camera..... color saturation can be adjusted quickly in the Optio and the ist-D by using the cameras' presets. On my Optio 330 "high" saturation is like using Velvia (very red skin-tones, highly saturated color), "normal" gives good skin tones. I have never used "low".
The real advantage of the ist-D is that you are not stuck with a 5x zoom. Lens choices from 15mm to 1200mm are possible (yeah, yeah, multiply everything by 1.5). The optio 550 gives you a 37-187mm zoom. I think the consensus is that you can print really good 8x10s with 6MP, some have suggested that 11x14s look good too. I'm sure 5MP will give you a good 8x10 as well.
