Niklas Savander thinks the company can't add enough value to make them worthwhile.
Nokia executives have been facing a barrage of questions recently about why the company doesn't abandon Symbian and MeeGo in favour of Google's Android OS.
EVP and general manager for markets Niklas Savander has restated the company's opposition to such a move, in a long and interesting interview with CNET.
He describes Nokia's "very strong belief that we need to be more than just an electronics manufacturer" as the reason for not adopting a fourth mobile OS after Symbian, Series 40 and MeeGo.
"We need to be confident that we can add a significant amount of value on top of whatever platform we choose," says Savander.
"Currently, we don't think the platforms out there which we are not using - Android and Microsoft - offers an incremental opportunity for us to add value that would sustain a competitive advantage over somebody else. So, no plans."
That said, plans can change, especially when there is a new CEO taking stock of the company's strategy. That said, Stephen Elop has also publicly stated that Nokia remains committed to Symbian and MeeGo.
Elsewhere in his CNET interview, Savander says that Nokia sees Symbian extending down into its cheaper handsets; that it has no plans to bring the Symbian OS in-house; and that Nokia's Booklet 3G netbook was disappointing in terms of pure sales, but "money well-spent for trial purposes" as Nokia mulls its approach to the tablet market.
