If you had said Sony W100 and Canon SD900,
I would say it is a toss up.

The Sony W200 was just announced and may not be in the stores yet.

It offers several improvements that sets it above the Canon SD900.

The Sony W200 seems to have the same lens system as the W100, but has added image stabilization and more megapixels.

Plus Sony is getting into high definition.

Since money is not a problem, you may be interested in the DSC-W80HDPR kit.

It bundles a DSC-W80 camera and Sony?s DPP-FPHD1 printer package. This package consists of the VMC-MHC1 high-definition component cable, a Cyber-shot cradle, a remote commander, and a digital photo printer with high-definition component output.

Here is a link to the press release on the W200:
