Good camera to start with?

I'm currently using a canon powershot S3 IS and it's nice but I have to share it with my mother. While she doesn't use it as much as I do it'd be nice to have my own camera. I've got a fair amount of experience with this camera so I think I might able to handle something more advanced. Any suggestions under $700, preferably either canon or nikon?

How to turn NEF files into JPEG files?

I have a D3100 Nikon camera that I just got and had taken almost 900 pictures on the memory card that I have and downloaded them all onto my computer. I'm trying to upload them to walgreens.com but it wont upload the NEF filed pictures. How do I change the format of these NEF files into JPEG files? It seems like the NEF files are like 4 times bigger than the JPEG ones and I just don't get it.It's getting quite frustrating.
Thanks :)
