Gaucho - Not sure what machine the PCWorld author was using but the T41 does not have a multi-bay that accepts the normal IBM devices. The T-41 has the newer slim t-4x series bay that holds either a cd-rw/dvd or dvd+r drive.
Because of this error I am discount the entire review by PC World.
Overall my T-41p is the best laptop I have ever used. I have a T40, X31 and T30 in the drawer that were all great machines but the T41p is the best of the bunch.
Back to the topic - the X40 is very cool machine and is a bit smaller than the X31 it replaces. I miss the CF slot as I don't have many SD devices yet.
