Nice to see you over here! So you up and moved to Montreal? It's kinda cold up there, isn't it? But the Quebec women might make up for that, huh?
So your old Coolpix kicked the bucket, huh? Those are classic digital cameras, now. I think there will a soft spot in many an old (30 years old?) photographer's heart for Nikon 900-Series cameras. But we must move on and accept change. Let your camera go the way of V-brakes. There are better things to be had.
Ok. Enough poetry bs. The one area that the Coolpix 950 is going to be hard to match is macro photography. You're going to have to let that go. If you really need the kind of macro ability your 950 had, you'll need to buy a conversion lens. Aside from that, I think almost anything you get is going to be better. Digitalcameras have come a long way in the last couple years.
If you go by the reviews here, you should get a Canon. If you go by overall sales, you should get a Canon or a Sony. Since you're already leaning towards Sony, let's take a look at that. Memory Stick. Yup. It's cheesy that Sony tries to make you use their proprietary memory. But they're starting to loosen up with their high-end stuff. And the image quality of their cameras is arguably as good as any manufacturers, in the compact digital market. Take a look at the new W7: http://www.pcphotoreview.com/6,Megap...7_5648crx.aspx
And here are a few more for you to take a look at:

Casio Exilim Pro EX-P700: http://www.pcphotoreview.com/6,Megap...5_5648crx.aspx
Let me just admit that I'm a fan of the 7 megapixel sensor. I think it's the best thing to hit compact digital cameras in a long, long time. The image quality is absolutely stunning. It's not the resolution. It's the actual image quality. Anyway, most cameras will be faster than your 950 and image quality should be better, too.
Just in case you've been thinking about an SLR, for you, my friend, I would recommend the Olympus E-300. That's my idea of the ultimate bike camera right now: http://www.pcphotoreview.com/Profess...1_3127crx.aspx
I know I didn't tel you what to buy. But I hope I gave you some ideas and direction. I expect you'll be back with more questions. And we'll be here to help.
