First of all, I'm not advocating that iPhones are better. I wouldn't have bought an N770 in the first place, nor continue running GNU/Linux on my desktop as my sole OS (10+ years running). No need to lecture the concept of open source to me and there's no need to belittle the people who prefer more closed systems.

I hope for your sake that the N900 has reached the critical mass level for it to sustain its developers. If one day Nokia releases new hardware and offers its developers discounted hardware to move on, then hopefully you'll have enough people left, people with enough knowledge to keep the OS/apps going. And if you find yourself buying new hardware to keep current, then maybe you'll understand what I was getting at.

(By the way, you should read up on jail-broken iPhones and their developer community. They have a closed system, but they're pretty resourceful. They've been actively patching up shortfalls in the iPhone, like adding multi-tasking on their own to iPhones that Apple doesn't support multi-tasking on.)
