Since you asked so nicely...

I'm not going to go on a run down of my preferred camera type or the different size lenses that I drag along with me. There is a huge variety of options in that category and just as many opinions. I'll simply mention that, in my experience, its best to pack one multi-purpose lens (18-200mm), which sacrifices a bit of speed for versatility. Depending on where I am traveling and what I estimate I will need, I pack 1-2 more faster lenses.

With speed and versatility in mind, I carry all of my stuff in a Lowepro Fastpack 250 bag. The Fastpack is not huge, but not the smallest camera backpack I own. The benefits are that it holds a 15" computer, has a top compartment for all sorts of odds and ends, and has a very quick-access padded bottom compartment for camera gear. I have tested out other camera bags that are similar in size and function, but the reason I like this bag the most is the convenience of quickly accessing my camera without having to put the bag down on the ground. The bag looks like a standard backpack so it doesn't advertise "expensive camera equipment" like some bags do. I do have a couple minor quibbles, one being the fact that there are no tripod straps on the bag. This is a big oversight in my opinion, but not a deal breaker. The lesser quibble is that the bag doesn't come with any sort of weather cover.

I use a Slik Sprint Pro travel tripod when I'm on vacation and not wanting to drag around something heavier and more cumbersome. When collapsed, the tripod is just under 20" in length which means it can fit into most carry-on luggage. It also weighs under 2 pounds, so it doesn't add to your overall luggage weight, either. The legs have three different positioning angles and it has a pretty decent ball head. Slik do not recommend using the tripod with heavy lenses, but it handles my camera with its 18-200mm lens just fine. Due to it's size, it's not the most solid tripod, of course, but it's an amazing tripod for traveling. I recommend purchasing a quick disconnect plate to attach to the ballhead for easy attachment of the camera.

For digital storage, I generally bring my laptop and a small, portable, external hard drive. There are times when bringing my laptop is just not feasible, however. And at other times, I need something "in the field" to which I can backup my memory cards. I use a Epson P series multimedia storage device. It's very versatile, with the capability to play movies and music, but I use it just for image backup. The large, bright 4" screen makes it easy to view your photos with greater detail than the camera's display. And it's simple to just drop a memory card in the slot, click the button to back-up, and then let it sit and do its job. It automatically turns itself off after a minute of inactivity, so you don't have to worry about babysitting it.

I use an iPod Touch for all my travel entertainment and communication needs. It does videos, music, games, translation, currency conversion, reading, email, internet, voice communication (Skype), and is pretty much the all-in-wonder device I desired during my years of travel. I have a Kennsington backup battery which does a great job of recharging my iPod on a plane or in an area where I can't get electricity.

Other minor equipment that I carry in my camera bag are: rechargeable battery and Energizer compact charger (for flash, GPS, etc.), a small Energizer flashlight that expands to provide lantern capabilities, a small headlamp, a external flash unit for my camera, a small diffuser for the flash, remote flash triggers, a rocket blower (for cleaning the dust and other crap from my camera), 4 extra camera batteries, a camera battery charger, lens hoods for my lenses, a couple lens filters (circular polarizers, graduated neutral density filters, etc.), a plug and cord for charging my iPod Touch, one of those goofy looking face masks for sleeping, ear plugs, band-aids, ibuprofen, diarrhea medicine, hand gel, small Moleskine notebook, 2 pens, a sunscreen stick (kinda like a glue stick, but with sunscreen), a pack of tissues, a plastic, waterproof case for my camera memory cards, a shower cap (for keeping my camera dry in those unexpected downpours), a photocopy of my passport, a small bag full of various power plug adapters for different countries, a small airline headphone adapter (for those lame 2-prong airline jacks), and sunglasses.

(Dang, that last sentence was one long run-on).

All of the above fits nicely in my Fastpack 250. The small stuff - like batteries and such - get packed inside of smaller, modular, accessory pockets, which keeps my stuff from getting lost in the crevices of the bag.

Anyway, I hope that helps. I don't mind going into greater detail on any of the above, if need be.
