Speak of the devil! I just posted a short post of my impressions with Mandriva 2009 in the 'Other OSes' section just a few minutes ago.
Glad to see you gave it a try, Anurag!
I haven't noticed some of the problems you mentioned, but then again I don't do heavy video usage, use Firefox spell-checking, or some other things. And I do agree the mouse cursor could've been better. But I must say, the artwork is fantastic!
