To be fair, I am yet to meet a phone that IS reliable.

The N900 is no worse than anything running Windows Mobile or the iPhones, because it keeps everything running when in standby whereas those two systems turn off WiFi and pretty much shut down. So to a certain extent I can forgive it needing a reboot every now and again, because it works so much harder than any other device I have seen and even desktop Linux needs a reboot every now and again too. The difference is the N900 it seems harder to restart just certain parts of the OS whereas desktop Linux you can sometimes get away with just restarting the malfunctioning part rather than a complete reboot.
