IBM UltraBase X3
The IBM UltraBase X3 is a portable dock for the X30, X31 and X32 ThinkPads providing extra ports as well as a bay for an optical drive and a set of stereo speakers. Containing a full featured UltraBay Plus 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 X3 also features a battery slot on the underside that accepts the same battery as your X30 Series ThinkPad. The UltraBase X3 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.
