Yeah, there are things you can do with the Elk like add a W800RF32 to use X10 palm pads and wireless door sensors. However, the $100 to add the serial expander board for one device and the manual set up involved (e.g. actually inputting things at the protocol level) make no sense compared to a PC. Of course Premise has a free opensource W800RF32 module, so adding one is a point and click exercise The nice thing about a PC is I can have as many serial devices I want for under $20.
Further, things like A/V receivers, TVs, Projectors etc usually have RS232 ports. While you can probably implement simple things using ElkRP like power on, etc, it would cost a lot more, be a lot work and not as versatile.
With Premise, all protocols are implemented at the module level, so this makes adding things very easy (assuming a module for the device is already posted). It also makes macros a simple point and click exercise.
Of course, I'm not even mentioning the lack of ip control with the Elk. Elk cannot control IP based devices, while a PC can. For example, I use the OBi110 with my phone and get a lot of information from sniffing syslog log packets. There's a free module posted for Premise, that makes setting this up very easy.
