Initially, I was disappointed too when I found out that the X1 required a Macro to shut down the PS3.
Then I started thinking about it; most of the time I want to shut the thing off with my Harmony I will be in the middle of watching a DVD (or at least at the DVD menu). If I'm already at the XMB it's really not a chore to get to the power off option. I tried using macros and I noticed it doesn't always work too great if the PS3 decides it doesn't want to get back to the XMB right away; you can miss the sequence.
So, I just programmed my PS3 device on my Harmony One (which I am using instead of the Schmartz to get the "fancy" icons) to have custom power settings which will send "Stop" and then "X" at power off time, and then set the power management of my PS3 to automatically turn off after 1 hour. The "Stop" and "X" gets it back to the XMB, and after an hour (or whatever you set the timeout to) it will turn itself off.
I also find this is convenient if say, I switch to TV, discover nothing is on, and then want to go back to PS3... If I had used the macro it would be off and I'd have to get up. You could also increase the delay time so it would stay on longer.
The best part, I don't have to deal with techs at Harmony!!! I have to say I wish there was a "pro version" of the sofware that would let some of the more technically inclined people into some of the backdoor stuff, but no such luck.
Thanks Mike for a slick looking product that functions really well!
