Although i mostly agree with what you said (ok to be angry, but throwing toys out of pram is stupid), it's not hard at all to switch devices that often. Once you bootstrapped the process with an expensive device you can start trading. Just exchange N900 for some other high quality phone. Some people who are actually running into some specific PR1.1.1 bugs every day might find it a good solution to trade it in for some blackberry or android and trade back with someone else once you can get PR1.2.
If you have enough time for stuff like that...
