@Goineasy9: Don't confuse people, currently all N900 uses Maemo.
@mfillpot: yes, you can download and install MeeGo on N900, but it still has different problems and is not very usable, it is more dedicated to early testers and developers.
@hoseini: It's not clear when it will be used by default in mobile phones, because currently there is no phone that is dedicated for that OS, only N900 which has no official support from Nokia. You can check what are MeeGo 1.2 release plans here http://wiki.meego.com/Release_Engineering/Plans/1.2
Looks like that first phone with MeeGo OS will be released only next year (probably in the beginning of summer).
Thank you for the update.
Are there any specific devices that the developers have been able to get meego to run stable on at this time?
