Oh yeah. Several.
Kata R-103 - very well padded backpack, carries a decent amount of DSLR gear + laptop. My usual bag for trips + travel photos - very secure (would be hard to steal anything out of it without being quite obvious), fits easily in overhead bins. Expensive but worth it; the padding is super thick and it fits a good amount of gear while keeping the overall size down and having decent access to the equipment.
Think Tank Digital Holster 20 + multiple sizes of Modular Lens Changers + Pro Speed Belt = awesome, versatile. If it's just the 5D and one lens, the Holster works on its own with the shoulder strap or attached to a standard pants belt. I can also add one extra lens (usually a smaller lens like the 50mm/1.4) in a small Lens Changer hanging on the shoulder strap. If it's dedicated photo shoot time, then I'll have the belt (with holster) and several extra lenses ready at hand. And I can toss any/all of this into a normal backpack, suitcase, briefcase, etc. and have my gear protected/worry-free even in a non-photo bag. TT stuff is definitely expensive, but it is top-notch and worth it. I love the modular aspect, it allows you to pick and choose what you want to carry. It is great for travel where some days you want just the camera + 1 lens while other days you want to carry a wider array of lenses.
Crumpler 6MDH (and generic $20 knockoff) - This is a great over-the-shoulder bag, I highly recommend the Million Dollar Home series if you want a shoulder bag. A 6MDH is big enough to hold a 5D + quite a few lenses (I think I used to fit all of my lenses, save the 100mm Macro, and a 430EX in the 6MDH). However, the problem with shoulder bags (and the reason why I sold my official Crumpler in lieu of a knockoff) is that they get tiring/sore to carry before too long. Especially if you have a lot of gear.... the problem with ANY bag is that it's easy to buy a big bag and then fall into the trap of having to fill it up each time you go out. So you end up carrying 10 pounds of gear putting all of that weight on one shoulder. It's ok if you just need to transport your gear someplace and can set the bag down somewhere when you get there, but if you're doing a lot of walking/carrying then you will want some kind of backpack or other way of carrying your equipment. The TT belt system above works great, you don't feel the weight at all. The Crumpler bags are certainly very stylish though, and are great for protecting your gear. I use my knockoff every once in a while.
Pelican PCS-247 - This is not a standard hard-sided Pelican case (although those are awesome) but rather it looks like a normal carry-on roller suitcase. The inside has a ton of dividers and organizers for a lot of gear. This is what I usually store my gear in when I'm at home, or use it to transport gear in my car. Plenty of room for ALL of my stuff (minor accessories included) and a good centralized place for all of my camera gear.
Wish/want to buy a sling bag. Probably a small or mid-sized one like the LowePro 100AW or 200AW. Big enough to carry a body and maybe 3 lenses total, plus some other stuff (book, rain jacket or whatnot) but not enough to weigh me down. I do like the sling form factor in theory, but am kind of leery on spending the money on something that I might not end up liking or being comfortable carrying. Especially given that I have so many other nice camera bags already.
