I used my N900 until a week ago, I finally moved the SIM card over to another phone (a dual-SIM one), because the (original) battery didn't take much charge anymore. Hardware-wise it's as good as new (mine is Made in Finland). Over the years I've used it to do support work in Antarctica using VPN from whatever cafeteria I was at at the time, other types of work where I needed a Linux computer and only had the phone, it's been running my minicomputer emulator, I did development work for it (the SDK running on my PC - basically a Debian setup), and, of course, as my phone. The MicroUSB socket was a weak point, the fix was to file off the two notches on microUSB cables before using them with the N900. So my N900's USB socket is still good as new.
