The TSWx60 has a nice screen saver feature.

You can control wake and sleep... this is essential for doorbells, cameras, security, etc...

You can remote load... you can to the processors for iPads but some times it is better reliability to load directly to the iPads which you cannot do remotely (easily).

Side buttons...

Touch detection, audio (we use sounds for notifications and doorbells), monitoring, rebooting (we auto reset the panel every night to clear memory for camera streams, etc...).
