Logitech z680 VS z560

Can anyone tell me the differences between the Z680 Z540 other than the Z680 has 5.1 speakers. The Z560 is rated very well and only costs $139 but as 4.1 speakers. There is a huge price jump for the ($290) for the Z680. Does the Z560 have digial input? Why is the Z680 so much more?

Also can anyone tell me if the center channel is all that important?

Well I made my decision and got the z560. At $140 what was I going to do.. Not buy it. Everybody raves about it. I could have gone for the creative sound works 550 at around 210. It has 5.1 speakers. But I had a hard time paying 70 more for the extra speaker. If anyone can tell me that the center speaker is really important to surround sound. I can still cancel the order.
