Oh dear. Like the N8 before it, Nokia just confirmed to us that the Symbian-powered E7 slider will be delayed. The official word has it launching in early 2011, not December 2010. We've been told that Nokia's holding up production due to a "minor durability issue" discovered in the E7 hardware. We can't blame Nokia for wanting to ensure the best possible user experience -- it's just a shame that it will require the holiday shopping season to sort it out.
