http://www.engadget.com/2011/06/16/o2-uk-spurns-blackberry-playbook-cites-issues-with-end-to-end/ Today is the PlayBook's official launch day in the UK, but one of the island kingdom's biggest mobile players won't be taking part. O2 has apparently been reaching out to subscribers who've expressed an interest in acquiring RIM's 7-inch tablet on the network with word that the company "will not be selling the device." The communiqué to those users states that "unfortunately there are some issues with the end to end customer experience," though O2 continues to work with RIM on future PlayBook products and releases and doesn't rule out carrying this particular slate in the future. We reached out for an official statement and the company confirmed that it has no plans to sell the PlayBook at this time. Maybe once it gets a native email client, eh?
