According to a report filed by Reuters, Nokia’s future tablet products may be lacking in one area, Microsoft software. Speaking to a source familiar with the Finnish company’s plans, the publication writes that Nokia is weighing all options when it comes to tablets, and its now moot smartphone operating system â MeeGo â is a definite possibility. A recent patent filing found in the United States Patent and Trade Office’s database has reignited rumors that the mobile giant will be releasing a tablet in the near future. This February, Nokia announced that it would use Microsoft’s Windows Phone mobile operating systems on future, high-end smartphones. The company’s tablet plans are, however, still unknown.
