My MX950 is and has been working fine for quite some time and I have been perfectly comfortable programming it and changing programs as my devices change.

If I needed to replace/upgrade it tomorrow, would the logical replacement be a 980 ? How different is the 980 programing software (CC I assume) from what I am currently using ?
I understand that I would need to ensure that I could get the software when I purchased the 980; is this as big a PITA as some threads would suggest ?

And finally, is there a version of the new software that works with a 950 ? I have not upgraded the 950 software in quite a while.

Thanks !
