OK lets return this thread to topic and civilised conversation.

Portrait mode only available or phone:

The N900 was designed with landscape in mind, this is not a bug. Portrait IS supported by the OS itself but only the phone currently supports it. The Internet browser is confirmed as being upgraded to use it in the next firmware update.

Third-party software can easily support either mode but mostly does not because landscape is a more "computer" style way of working and unfortunately there is no portrait on-screen keyboard by default. Also the N900 is based on Linux, plenty of software comes over from Desktop so is designed for landscape use ONLY. It will take time for software designed for the older tablets and desktop to be adapted to be more "phone-like".

Believe me I really wish conversations supported portrait as I often type one-handed on the bus/tram. However it is by no means a deal breaker for me.

Alarm and ring tones through bluetooth only, if bluetooth is on:

I assume you mean if your headset is paired and switched on. Surely it does not do this if bluetooth is on but your headset is turned off? If it does, then that clearly is a bug.

If it does not however then why on earth are you leaving your headset turned on when you are asleep in bed? Surely it should be turned off charging somewhere.

I would argue that the way it works makes sense, as why bother upsetting everyone else in the room with your alarm/ring tone if you are wearing your headset? Although it would be nice to be given the choice its a sensible default behaviour. There is little logic to leaving your headset powered on if you are not wearing it so its a fairly logical assumption that you are.

Overall, I am overjoyed to hear the N900 works this way. I always feel guilty when receiving a lot of SMS messages especially if I am doing something like queuing at the bank, as hearing the same tone over and over must be annoying for everyone else (I know it annoys me when someone else does it). The idea that it would redirect to my headset instead is excellent.
