the biggest feature that the mx980 has over the mx890 is graphics capability.  it takes longer to customize the 890, and graphics need to be stored in specific folders before you are able to use them in a file.   it is easier to do custom graphics with the 980.  the 980 can also display animated gifs, while the 890 does not.  

the 890 also takes quite awhile to download a file compared the 980.

i like the feel of the 890 though.  we have replaced the 980 with the 890 as our entry level remote for our installs.


yes you will need to program macros, and yes you can use the Punch Through section of the programming to make the volume buttons use the commands from your AVR.
