To me, sWords' table illustrates why there is no obvious alternative to the Pronto. I would put "firm buttons" as an absolute must have, so that cuts out Ipad, Android, etc. And I would also put "available to DIYers" as an absolute must have, so that cuts out AMX, Crestron, RTI, etc. So, that effectively means that there will only be an alternative if someone develops a phone/tablet with hard buttions.
