Bucking the trend I recommend Apple’s Time Machine: a part of OS X 10.5 Leopard. If you have no back up strategy Time Machine is definitely better than nothing! If you use ChronoSync or Carbon Copy Cloner then stick with them. SuperDuper! is expected to be updated for Leopard by March 2008.
A part of the Adobe Photoshop CS3 10.01 update includes the option to include XMP with Export for the Web & Devices. This means your JPEG images can retain copyright and other important metadata. Adobe Camera Raw and Lightroom are also updated; the latter now plays nicely with Leopard.
Phase One announce Capture One 4 is (finally) available. Sporting a new interface and limited DNG support Capture One 4 is a good start. Note this is the replacement for Capture One 3 LE. The Pro version is expected sometime in 2008.
