Well I took a peek over at Cisco today for the 3550 Documentation and there it is 12.1(11)EA1. Looks like there are 18 "NEW" IOS features for this release. Some of the more relevant for the lab I see such as: Support for Cisco IP phone, BGP, more QoS, Multi-VPN's. The more I read about this little box the more I like. This thing is a power house of features.
