Yeah, I saw that article a couple of days ago too.  If you read it 
thoroughly, what it actually says is that 1/4 of kit fails 
compatibility testing *before* being issued a WiFi certificate.  The 
kit is then sent back to the mfr for tweaking, and certified as WiFi 
compliant after it passes the testing.  And that failed gear can 
still be issued as "802.11b compliant", but not as "WiFi compliant"

Admittedly the opening paragraphs are a tad ambiguous.

In the 60's people took acid to make the world weird.
Now the world is weird and people take Prozac to make it normal."
