My n900 is a Frankenstein's monster of cobbled-together spare parts. None of my boards have working micro-usb, so I just keep a bunch of extra batteries and use an external charger. Unfortunately, without the ability to relfash, I'm must less experimental with it than I used to be.

And just this morning, my slider mechanism started jamming up.
Thankfully, I've got a few more in the scrap pile.

I will give up my N900 when you pry it from my cold, dead hands, or when I get a Neo900, whichever comes first.
