RIM has issued a statement to Erictric in an attempt to stymie reports that its forthcoming flagship Playbook tablet will is facing possible delays due to issues with its battery. Kaufman Bros analyst Shaw Wu made the claims and said that the issues revolved around RIMís use of the QNX OS, which was not originally optimized for tablet devices. RIMís statement refutes these claims and insists that any issues that might have been detected are only in non-optimized, pre-beta devices.
