Not sure what to say but my "old" 16 month 9890 is limping so last week I bought another 9890 to be ready for the Christmas rush. I've read many problems with the x890s and x900s so it does appear to be common. If I could get mine to last 3 years I would actually be jumping for joy but I have a serious dust problem that I am trying to resolve. A great website to look at for free advice is myx900.com as it applies to both versions.
