I've sat in many a meeting where the Macs "steal" all of the DHCP connections and I'm stuck watching the speaker instead of following TweetDeck.

I've had my wife's macbook bump mine off the network by stealing the IP my machine is using. Definitely an inconvenience when on skype.

The only time this should happen is if your router has been rebooted. Otherwise, the Mac is only reusing what should be a valid DHCP lease. If your router is handing out that same IP within the term of the lease expiration, you have bigger problems. If your router is restarted frequently, you should look in to a firmware update to increase the stability.
