Not to mention the (sometimes not so) obvious fact that the 3550 EMI can only handle ethernet interfaces... won't work for a T1 circuit... ;-)

3550 EMI has unupgradeable 64MB RAM. This is not enough to do full BGP
routing with ISP's. It's good enough to participate in an IBGP + IGP with
limited set of routes in a small end POP/ethernet colo environment though.
It also cannot do a few minor stuff that adds a little bit of annoyance such
as lack of uRPF, even though it takes the command properly.
The QoS/traffic rate limitation features are also restricted on 3550 if you
want to compare with a full blown router.
Further, Cisco has tradition of being slow or not following up to its pre
marketing claims on modular Layer3 switches. Don't expect exciting new features.
It is worth noting that 3750 had been advertised with IPv6 capability since
the beginning and still no IPv6? heh.
