Thanks for the help: if the new athk5 supports model AR5418 then I'm a
go for that,
As for the rest of the issues "nice, now you have me freaked out," "I
guess I'll have to use OSX," but then If I do
I'll have to listen to this voice in my head saying " use Linux" "go
ahead Justin use Linux" "come on what are you chicken",
kind of like putting you're full day's worth of work in; and driving
on the 405, Then all of a sudden having a voice tell you
to go grab a nice cold refreshment(B$%^r)
regards;
