I think you did the right thing in giving the pros and cons of the various systems. The other question to ask, IMO (and you may already have done this or know the answer) is--is this the first digital camera and how will you be using the camera--where, what for, will you print? I'm almost 70--I rarely mention it as it seems to automatically create a stereotype of me in others minds LOL. But--my choice of a camera, having shot for many years including film, and someone of my age who's choosing their first digital camera would be different. I also rarely use a camera for snapshots/casual shooting and that may very well be the primary interest for other older photographers (and I'm used to lugging heavy camera gear on hikes, urban shots, etc)--so size/weight, IS and portability may be a major concern. I've also found that a number of newer/older shooters really don't like changing lenses--that's a consideration for either choosing a kit lens or fixed lens camera.I too, take care when making recommendations and in my first email back to him it was the pros and cons of each system. I definitely found from my forray into the Nikon world that the lens selection could either be disappointing or very big and heavy. Canon really doesn't seem to be that much different. Oly seems to have a much better lens lineup. Etc.
Where I think we differ a bit is that I believe even without the desire to use legacy lenses a G1 14-45, 45-200 and 20 f1.7 (assuming it is good) makes a very compelling kit.
Also, if the lens is good, the two lens 14-140 plus 20 f1.7 could also be a great set-up for a lot of people.
Every so often, try and pop off a shot or two using intelligent Auto. I think you will be surprised at how well the exposures come out.
I agree about the 14-45, 45-200 and 20 f/1.7 being a good setup for those of us without legacy lenses. I became interested in the G1 initially because I wanted an alternative to my 5D for long periods of carrying gear when photography isn't the main goal (hiking, full days of carrying camera gear in urban areas) and had tried the G9 and a used 400D/XTi this past year. I wasn't happy with either and so started following first the Sigma DP1 and then when the announcement of the G1 was made I made it a point to learn what I could about it.
I finally decided to buy the G1, am enjoying the 2 Panny lenses and know I need a fast standard particularly for my own needs--and probably a wide if I don't want to carry Canon gear. I may--or I may not--buy alternative lenses and adaptors--that decision will probably come after I see what Panasonic (and Olympus) come out with this year--or at least what they announce will be available this year--the earlier the better. I don't plan to sell most of my Canon gear--I have lenses I won't part with soon and situations I still feel I would rather shoot with the 5D, but, as I wrote on another forum--I am feeling much more confident shooting with the G1--and the level of 'fun' can't be beat *smile*.
