CameraLabs have just reviewed the Canon 17-40mm f/4L lens.

“In this review we’ve concentrated on using the EF 17-40mm with the full-frame Canon EOS 5D, where its enormous wide angle coverage can be truly unleashed. We’ve compared it against the EF 24-105mm f/4.0L and the older EF 24-70mm f/2.8L, as many photographers will actually consider using the EF 17-40mm as their main general-purpose walk-around lens. While it clearly can’t zoom-in to anything you’d describe as telephoto, the 40mm ‘long’ end makes it more flexible for day to day use than you’d think.”
