im going to have to disagree with you on this one. him getting a G9 or something similar will just be wasting money/putting off the inevitable. i think a great way to learn the basics of photography is to get a beginner dslr and just start messing around with it. also, with the size of new dslr's these days, you dont need to get a big bag...unless youre gonna have a plethora of lenses. for example, i think a D60/D80 with a 18-200mm VR is a great starter setup, and its not even that big.
Fair call the base dSLRs are pretty small. I consider the prosumer p&Shoot cameras a 'gateway' to a dSLR.
But consider someone who is used to taking a shot with their cell phone starting to use an dSLR. It can be a bit overwhelming, and may squash their interest.
A prosumer Point & Shoot gives you the freedom to consider your composition and approach without the learning curve or the weight/hassle of a dSLR. You can take it anywhere and shoot almost anything, then drop it back into your (pretty bloody big) pocket.
After all, it is about the shots you take, not the gear you use.
If you like it, no doubt you'll end up with a dSLR - in which case buying a G9 was just avoiding the inevitable...
But would you have enjoyed the ride so much if you had to carry a dSLR around? I'm not so sure.
I think that going through something a bit less cumbersome is a smoother ramp up, and is more likely to keep you enthused about photography in an image making sense.
In a creative, non technical way.
To give some perspective - I've a 400D with 17-55 2.8 IS USM and a 70-200L f4 IS USM, both heavy lenses on a light body.
I love it... but I definitely wouldn't recommend it to someone starting out.
Too much bullshit and weight to enjoy photography in a simple sense.
At any rate, if you're considering any Canon gear and don't mind it 2nd hand, you shouldn't look past this forum:
