UltraBase X4

IBM UltraBase X4

The IBM UltraBase X4 is a portable dock for the X40 and X41 ThinkPads providing extra ports as well as a bay for an optical drive and a set of stereo speakers. Containing a full featured UltraBay Slim slot, it provides flexibility in drive choice as well as the option of a secondary battery for extended working time on the road. The UltraBase X4 doesn't provide a second docking port as the original UltraBase did, hence you can't dock the UltraBase to any of the other docking solutions.
