Anyway, going to explore Kaiser. :)
thats what many design work are done to prevent users from doing things dangerously. If you've noticed, that all phones SIM cards are hidden under the battery and/or blocked by the battery in one way or the other. That's to force user to shut down the phone before doing anything with it. I'm sure that's for the protection of the SIM and/or not making a mess on the telco system, which may heavily affect the phones popularity
Just got my Kaiser, lovely boxing, lovely phone but I've had a little unpleasant surprise - I've entered SIM card while phone was already on. In result Kaiser have just crashed - I mean switched off itself. Anyone else noticed similar trouble? Does it mean there is still need to switch the phone off before changing SIMs?

The hot-swap SIM slot is a very good solution, especially for users having more than one SIM. It allows you to exchange SIM cards without the necessity to switch off the phone and remove the battery. It is enough to switch phone in offline mode while changing card. At least it should work and it works on N90 just fine but on N93 with the current firmware version it is impossible to remove the SIM card even in offline mode because it causes prompt freezing.
I've also had the Kaiser for a couple weeks now, and yes, it is supposed to shut down when you open the SIM cover. It's just for your own protection, you can even break your SIM if you remove it while the device is on (and, has a electric current flowing to the SIM).
