Can you put Microsoft Word on a Nintendo DSi?

Perhaps, in the future. Nintendo is coming out with apps compared to the I-Phone. In the next 5-8 months, new software will be available. A YouTube app, Video Streaming app, and Facebook app will be available soon. Microsoft Word has been considered, but Nintendo will find it difficult to sign a contract with Microsoft, because it is a full sized computer company, not for smaller devices, but that can be changed.
