If I switch the device off (or let it turn itself off) and just leave it lying htere, the battery will slowly degrad, but it takes about 4 weeks to go completely flat.

It wasn't "off". It was suspended. There's a big difference.

Yes. My Zaurus SL-C760 does this. The "power" button suspends the system when pressed, powering off the screen, remembering the memory state and powering down the procesor.

But we aren't supposed to need to do this. The iLiad, being a single use device, should suspend when not in use for a period of time. A button pressing event should "wake" it.
From experience with many devices, I can tell you that the LCD and backlight use up the vast majority (and I mean VAST - like 75%+) of the power of the battery. eInk devices do not have an LCD and backlight and, so, the only power savings left are the processor and any peripherials.

Heck, I'd like the ability to just turn these off and leave them off.

If there is no Hardware Limitation in the Iliad, this would give us about 3-4 weeks of "Standby" and a lot of pageturns in reading mode...

I believe that if iRex knew how to do this, they would have done it already. This is what I would expect in an eBook reader.

As I said, there should be no issues with this. My Zaurus, running Linux, already does this (more or less).
