Well, I'll try to go along the lines of battery grip irrespective of what model you will be using today or the future:
Advantages
- Better grip
- Balances the setup when you couple a heavy lens and flash head
- Vertical framing convenience
- Allows for 2 batteries for longer usage (not necessarily double the operating time)
- More power supply choices and flexibility (battery pack and AAs)
- Minimize motion and vibration caused by your finger pressing the shutter too hard
the above bolded does not apply to some battery grips, like the Sony ones for example.

Disadvantages
- Although heavy is good, it is bulky and a lot of weight
- Your bag may not fit the camera+battery grip, which means you either need to dismantle it before going to the bag. Alternatively, you need to de-couple lens.
- When you rest your camera on a surface, the battery grip causes the camera to be too tall and the lens is not supported. Causing it to tip down, with your lens filter thread and mount taking a lot of downward stress.
yes, some bags don't fit it. i have to abandon my old bag (small lowepro) because once you have the grip on, the most you can put is prime 50mm. any other lens, sorry la no place to adjust.
as to the camera tipping, it depends on what lense. kit lens and prime lens (50 1.8) are usually fine. they won't tip.
here's the 18-55 on 350D + BGE3
on the other hand fit with any of my other lens - sure tip. because they're heavy. i don't think the stress is that power lah. in most cases, the filter doesn't touch the ground. like my lenses for example, only the hood touches it.

Although the disadvantages are valid and true, you can counter it by changing your approach in handling your camera. EOS 30/40D camera might not need a battery grip so soon because it is a large body to begin with. The EOS400D is simply too small for our hands and when you do framing, your left hand will be tired because there is no battery grip present there to support your left palm.
well if you enjoy the convenience of a grip in taking portrait shots, then having BG would be nice. it's not just the weight la.
this is how you hold without grip

try doing that for long period of shots. i did that when doing runway shoot. after that my index finger hurts and i had to use middle finger for shutter. no kidding.
because you know la when it's packed, you have to hold that way, tip toe, balance. focus / snap, and hope your arm doesn't block and armpit doesn't irritate others.
