Mine was Nokia N-gage QD, i bought it second hand for 5k in 2007 just to play ngage and gameboy games. I still use it but don't play games anymore. My 512mb card died, so stuck with 32mb mmc. Want to buy a new card but not available locally and the ones on ebay cost 1.5k.
This smartphone is still serving me well and don't see any reason to upgrade apart from the camera part.
