I've used this lens and have really, really liked it. That said, if the 24-70 II (2.8) or any of the 70-200 (2.8/4.0/IS/Non-IS) are in your future, you may not really need this lens. It's a great kit lens for all purpose use, but the lenses I listed above will keep the 24-105 on your shelf unless you use it specifically for travel.
Of course, if you have no plans for any of those other lenses, and you're short on investment into this hobby (won't say business, b/c if you're in the business, you'll likely use the more specified focal lengths) then this 24-105 is a great start.
Sometimes it's important to understand exactly how much you don't know.
Don't use SnapSort, don't cite SnapSort. (WikiPedia, on the other hand, is actually pretty good. Don't dis WikiPedia).
