Dangling WiFi-carrot meet your BlackBerry-made stick: the Z10. Perhaps because its user base has traditionally courted strong enterprise support -- a lot that typically overlaps with the jet set -- BlackBerry's offering an incentive to adopters of its BB 10 pearl, granting gratis Gogo-powered internet access for all domestic Delta flights. The best part? Latching onto that free WiFi is as simple as logging in and firing up the browser on your Z10 when it's "safe to use your electronic devices." Will this tip your hand and get you to switch to BB 10? Probably not, but it's the sort of pot sweetening that should keep BlackBerry's (moneyed) customers around for the long-haul.
