What's the punchline?

Someone failed to tell Guy Kewney over at eWeek about Vocera before he wrote his article, Voice over WLAN Still a Joke That's Not Funny. And I suppose he also failed to do any background research into the matter and missed the recent tests by Vonage of Voip over Verizon's EV-DO network. Not to mention the trials that IDT Corporation currently has underway of VoiP over Wi-Fi in the Ironbound neighborhood of Newark, New Jersey. So why does a reporter blast a technology based on a trade show floor demonstration? Is there something going on here, other than sloppy journalism?
