I own both the 8090 and the new 9800. I have not noticed any appreciable improvement in the range of the 9800 over the 8090. The key layout is good for both. One handed operation is ok too. Both of these remotes do the job I need them for, barely. Since there is no better alternative out there I have kept them.

My complaints with the 8090 are that it will not support one of my devices and OneForAll does not offer an upgrade for it( A Sony Preamp). Otherwise I have been able to set it up in a manner that is very convenient with key re-mapping and macros. The RF range is about 60 feet with no walls. From there subtract about 15 feet for each wall you have to go thru. I know they advertise 100 feet RF range, but I have not been able to duplicate this.

The 9800 is identical to the 8090 except that is has six learning keys for each device. There are 8 devices offered so there are a total of 48 learning keys. This solved my problem that I had above with the Sony preamp not having a code but it also used up all the memory available after I used up all the learning keys, remapped a few keys and put in two macros. This remote needs more memory and ALL of the keys should be learning keys. If they could do this, along with support for 10-12 devices instead of 8 it would be a killer remote.

ABye
