I still love my N900 coming up to 6 years after getting my first one. The only reason I'm not still using my original is that the FM transmitter was DOA when I got it, and it crashes very easily with overclocking/undervolting.

A few years ago I picked up a 2nd one very cheap and that's my daily driver.

Obviously 256 MB RAM is a bit of a joke for modern web browsing experience, but worse it the fact that many modern sites simply won't render with N900's now ancient browser. Still there is Opera Mobile and Opera Mini that will allow use of some sites.

I keep finding awesome new stuff that I can do with my N900 ... or apps I somehow hadn't heard about until now... like the N900 port of Zim.

I'm even writing a PyGTK app right now on the device itself via SSH and tmux.
