IMO anything P.C. based has a use by date.
I am seeing this time and time again with the p2000 system
Backwards compatibility always has a use by date. Unless any company can "guarantee" they will be around when technology will dump the current day standard and they will make non cost efficient backwards compatible hardware and charge you the earth for it because unless they do this it is not viable then their PC based system will in our life time die and not have an off the shelf replacement.

ATM anything USB is safe until the standard on P.C's are changed.
do you really think that in 10 or 20 years P.C's will actually have "any" port or socket other than the 240v or power pack socket (if they even have that) ?
sockets / connectors cost money so companies will phase them out and only support wireless or blue tooth until blue tooth becomes too slow and another style of wireless interconnection will become the standard.
