I got it yesterday. I personally like it. Sometimes I dont like to get out and turn on the mic (expecially when playing offline games) but people still want to mesage me...etc..dealing with turning on my wireless headset to corrospond when playing an offline game sucks.
PLUS I just tested and t works with FFXI.!!!
As far as messenger itself, I dont use it, so even without the use of MSN messenger, this KBD gets my $$ for being a great FFXI kbd alone.
