Man, Canon surely been busy working on new cameras… the SD450 is very interesting… I sold my PowerShot S100 (aka Digital IXUS), might pick up one of these SD450 is the CA (purple fringing) isn’t as bad as the SD400.

Canon PowerShot SD450 & SD550:
Two more additions to the Canon ultra-compact line are the new five megapixel SD450 (IXUS 55) and seven megapixel SD550 (IXUS 750). Both cameras feature a new wide viewing angle 2.5″ LCD monitor, DIGIC II image processor, Lithium-Ion rechargeable batteries and SD card storage. They also have a surprisingly useful new feature which rotates the image in display mode depending on which orientation you are holding the camera. These models will be priced at $399 and $499 respectively.
