That's exactly how I feel about it.

It does? Oh gosh, that's awful. I hereby predict that it will be soon
disabled, somehow. ;-)

That's another nice touch, in these days of diminishing privacy, and gives
the best of both worlds.

You want to keep it connected? Just leave it alone, and after a while the
screen blanks, while connections stay up.

You want to put it to sleep, away from world concerns? Just slide the cover on.

Very simple, very functional. It feels good.

The 770 cover also has an important protecting role: it is solid, and
always at hand, thanks to the very well thought out "sliding on the back"
mechanism. The auto-switch off when on the front, no button press needed,
is a very nice touch.

I'm sad that it has been dropped from the new model.
