It’s a bit odd when something so obvious isn’t even mentioned in passing.
Like The Verge, Engadget naturally made no mention of the HP Spectre One’s many obvious similarities to the iMac.
Big “gadget” blogs depend on maintaining very friendly relationships with the companies whose products they cover so they can continue to get exclusives, interviews, press badges to events, and early access to products. Maintaining these relationships while retaining credibility isn’t always an easy choice for many sites, and many choose poorly.
Update: I like Gruber’s theory as well.
