I think it a big mistake not to include an upgrade path. I argued this repeatedly when Crestron introduced Adagio; the Apad used a BB-1000 backbox that was originally designed for CT-1000 touchpanel. Considering the CT-1000 had been recently replaced by TPS-4L (which requires a different backbox), Crestron has once again failed to include a path for upselling - not just the wall touchpanel but the entire system.
