Actually, i like Amarok...but have a "fondness" for rhythmbox...it's a bit simpler interface and i like it's basic sound (even though it doesn't have an equalizer)...
K3b is outstanding and runs rings around brasero...i always install it on mint mint main edition...and yes k9copy, kdenlive among others are excellent as well...
For messenger, i do prefer pidgin over kopete...and actually, mail-wise, i recently began to just use my web based gmail with the chrome gmail notifier exclusively instead of using any software e-mail program...k-mail is ok...but even on kde, i had preferred to use my Evolution Mail...
There are kde programs that run rings around the gnome ones...but the reverse is also true, Bubba...For example, i like both totem movie player, gnome- m player better then dragon player...but i also very much like vlc media player which IS a QT program...but that is multi-platform not just kde....

That is why it's great that kde programs can be installed in gnome and gnome programs can be installed in kde...that way....you can get the best of BOTH...
I am using Mint 12 main edition now and very much like the direction Clem is going with Cinnamon...it's my main session on here now and it doesn't have all the features yet...that is how much i am enjoying it...
Good luck with mint kde12 no doubt the RC will be out soon...they just have to finish testing the 64 bit and then do the 32 bit iso in the testing...
