I understand "attachment". Some things do it for me, others never make it. I had the Canon 20D, XT, XTi, and 30D. I really liked the 30D and we did form an "attachment". Sold off the Canon gear and got the Nikon D90. A wonderful camera and better than the 30D; but I have never formed the attachment. It's just a very good tool.
I had the SD870IS and liked it, but traded up for the SD880IS. A better camera, but I didn't like it as well. Now I have the S90. It's taking a while, but we're going to be very good friends. I have also formed an attachment to the SD950IS. Pretty much redundant to the S90; but I don't care - I like it. Besides, it takes great pictures.
I've tried in other posts to explain this "attachment". For me it works with cars, hand tools, golf clubs, hi-fi gear, electronic instruments, and cameras. The G7 is one camera I got attached to. Also, the Pro 1 and the S5IS.
My all time favorite camera is the Nikon FE2.
