- Cisco IOS to Juniper JunOS transitions - why put up with a 100Mbit network when you can get all-gigabit (and more) for the same price? Plus, learning JunOS is really easy.
- Enterprise email: Cyrus IMAP is OK, but if your users can't (or won't) set up Thunderbird themselves, insist on a web interface, and you aren't able to outsource to GMail, there is no better enterprise MTA+MUA I have found than Stalker Software's CommuniGate Pro. Forget about Exchange.
- Virtualization / consolidation / storage: These three, which are all part of the same thing, should make it easier, not harder, to roll out new services, but you need to drink the whole pitcher of virtualization kool-aid, not just a cup here and there, for it to be really game-changingly useful.
- Tape backup: It's OK for some situations, but this is what your Grandpa used for disaster recovery. See "virtualization kool-aid".
- 3rd Party Bloatware: If you just bought Remedy, Weblogic, eHealth, Netbackup, or some such 3rd party bloatware, and it doesn't work, then ask for your money back, and spend your refund check to hire *us* instead.
- Building out a data center? I am an infrastructure guru. Measure twice, cut once. Including the BTU calculations.
- Finally, monitor everything and anything with Nagios, MRTG, and/or Cacti. Why spend tens of thousands to install and license proprietary 3rd party monitoring software, then tens of thousands more for their consultants to come in and set it up for you, when you can do the same thing for only the cost of the expert assistance?
