With the D60 you can only use AFS lenses, whcih if you don't plan on buying a lot of lenses could be a good thing. With the Canon you will be able to use EF-S lenses, which would include the 50mm 1.8 which everyone should have. You can get the 50mm in Nikon, but you won't be able to autofocus unless you get the AFS version which is a lot more money.
