Basically, i hate how the screen is facing me at, say 40 degrees, and then i accidentally tilt it sideways and if the the phone isn't dead-level, it rotates the screen sideways.

A second to reload everything on screen, shake the phone wildly waiting for gyroscope to realise i don't want it that way, wait again for screen to reload... *sigh*

another common cause is handing phone to mate to check something, and the phone just decides "HELL YEAH, GONNA ROTATE"... *sigh*

This is ridiculously frustrating, and don't start with "it's not hard to avoid" and "it's never happened to me" because with especially with the CSSU, portrait is almost everywhere, and there really should be an easily accessible way to set the "rotate-ability".

I'm aware of the new menu thing that allows it to be locked to landscape, but this is an ugly hack, and whenever a phone call is received, it destroys the refuse button.

also, (this is exclusively issue for CSSU/third party apps) if there is a chance for "rotate-ability" to be set, I would also like to take this chance to point out that the kernel should handle screen rotation how the web browser does;
if you rotate portrait upright (proper orientation for a phone call), it displays portrait mode.
if you rotate landscape upright ("NOKIA" in the bezel is right way up), it displays landscape mode.
if you rotate portrait upside-down (opposite for a phone call), it ignores the change.
if you rotate landscape upside-down ("NOKIA" in the bezel is wrong way up), it ignores the change.

This ingenious thought applied to MicroB is amazing in its usefulness, if you want the phone physically portrait-mode, but displaying landscape, you rotate wrong way for a phone call, and hey presto!
sorted.
(think when you're lying down in bed on your side, yet you still can browse web properly)

And honestly, this amazing thought in MicroB is totally absent from so many other devices (including iPhone), and it's just such a brilliant idea. All those people that dropped phones on their face whilst using them in bed, not us.

Not the N900.

It cares

ps, the N900's really quite heavy so ty for caring Nokia designers/engineers!
