Marco Arment on coverage of the HP Spectre One at The Verge and Engadget:
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.
Even when they do get exclusives and interviews, there’s not much to them.
