I must say I don't want another taskbar applet, I want a shortcut keypress that achieves the same thing as slipping the cover on the 770.

I enjoyed the ability to surf on a train right up until the train stopped, safe in the knowledge that slipping on the case was a two second job before I left my seat. Now with the N800 I have to faff aounrd with a tiny recessed button on top of the device (which doesn't actually achieve the same effect as putting on the case) and I don't want a taskbar applet as I may have to switch from the full screen browser to the home screen and prod the applet with a finger/stylus - all of which will take longer than is necessary.

No, what I want is a shortcut keypress. For example, holding down Home for 2-3 seconds, or double-clicking Home (the latter should be faster for those in a rush). This would have the exact same effect as putting on the case cover - there should even be the checkbox in the Connections dialog to leave the wireless enabled once the device is in "sleep" mode. Resuming from sleep mode would be accomplished by holding or double clicking Home again, or perhaps pressing two different front buttons.
