So it is a 100% guarantee that you will be on the right input, but it at least reduces the number of times that you will be on Blu-ray when you wanted to be on one of the HDMI inputs.
In passing, I mention that when this option recently first became available through a firmware upgrade I was very appreciative. In my setup probably 99.9% of the time I'm using my Oppo along with my HTPC WMC media center extender (Linksys DMA2100), running my TWC-provided cable content from the DMA2100 through the rear external input of the 103. So keeping the Oppo effectively "permanently switched to rear HDMI input on power-up" seemed like a good thing.
Well... HDMI handshakes, there you go again! The HDMI output of my 103 then goes into my Yamaha RX-V867 AVR, and then there's the second HDMI leg going from the AVR to my HDTV display.
Turns out there was a real "instability" in my setup depending on whether all of the multiple devices involved were fully powered up and operational/stable, as determined whether or not everything was "instantly working properly" or whether I had to screw around doing things like temporarily changing inputs (either on the Oppo or the AVR) or powering something off and then on again, etc. So this new "last input selected" option which I'd really been looking forward to... well, it actually seemed to be a "curse" for me.
So I went back to "BluRay player" as the settings option. By powering on the Oppo first (set to "BluRay player" as input), then AVR, then HDTV (Panny 65VT50) and letting them all "stabilize" in their own power-on sequences, and then power on the DMA2100 and wait for its own 30-second power on/stabilize period), and then switch inputs on the 103 from BluRay to rear external HDMI (and now have the multi-device HDMI handshake work perfectly through all power-on and stable devices)... well while this was a bit of an annoyance, at least it was guaranteed to work 100% perfectly.
So YMMV, as to whether or not choosing the "last input device" setting turns out to be a blessing or a curse. And again, it's the multi-device (i.2. 3 or more) HDMI handshake situation which is really the culprit here, as it may be performed prematurely and therefore may fail, depending on the setup.
