Well when I bought my t42p in June, the Intel chipset was only
supporting 802.11b, not g.  I asked IBM about it and they said that
Intel was very slow in developing 802.11g, which is why the IBM models
that support 802.11g have no "Centrino" trademark on them.
My guess is that they have different part number options.  You should be
careful when ordering to confirm support of 802.11g.  If you can get the
Intel chipset and it does support 802.11g, why not?  At any rate all I
can tell you is my experience with the Atheros chipset, which has been
fine.
