They're one of cisco's earliest (first?) inexpensive fixed configuration 
layer 3 switches, do per-port policing (ingress and egress) with pretty 
good flexibility (better than the 3560 which "replaced" them) and because 
they're EOL, they've gotten very inexpensive.

As CPE, I can see them being attractive where you need a router that's 
going to handle limited routes (preferably just default and maybe a few 
static routes, but with EMI software, they can do limited BGP4) but want 
wire rate packet forwarding performance.
