Ummm... Community SSU came out for alpha-ish testing about 24 hours ago, there's a system-wide portrait/landscape qwerty/T9 keyboard. What else happened somewhat recently? Injection driver patches were updated and went open source lately. Host Mode happened.

Not to mention wonderful smaller projects like Columbus, Sleep Analyzer, Advanced Clock Plugin, and so on, that aren't revolutionizing the device but make the N900 more enjoyable and so on. (Except it isn't just those three. Some new app pops up like every week or so.)

N900 developments dwained drastically in the last year my ***.
