I like the Nikon SLRs. YMMV -- plenty of people go gaga over the Canons.
Here's a handy
lens compatibility chart. Notice that the AF-I and AF-S lenses were introduced in 1992 and 1996 respectively. So while the motor issue with older lenses is definitely something to think about, "older" is relative, and IMHO it's probably not a deal-breaker unless you have a stash of old Nikon lenses or plan to buy a lot of new ones.
