Coldplay - do they have a 'best of' cd?

This will be a dumb question to all the music people out there I'm sure, but have Coldplay put out a best of cd yet? If so which one is it?

I really like Viva La Vida and also the older stuff ie. Yellow, The Scientist etc. Does this mean buying 2 cds?

Don't talk to me about downloading music, I haven't caught up with all that technology... I still listen to cds (no, no MP3 thingys or Ipods or anything). :p
mmmm... there is a discography 'floating' around. So I am told... indirectly... not that I know anything about that sort of stuff though :rolleyes:
