the X series has considerably better battery life, even with the 6-cell (google for various tests). i know the X220 (and maybe other X-series) also supports the "slice battery" addon, which attaches to the docking port and drastically increases battery life. i think it mostly hinges on whether you find the smaller screen acceptable.
