This is a bit misleading.
The Pentium M architecture may be similar to the PIII, but they are nothing alike in performance. Pentium IIIM and 4M were adapted desktop chips, for laptop usage. While the Pentium M was a clean slate design specifically for mobile application. Confusion is often added to this by errors in ads and press, as is the case here.
The above referenced T30 has a Pentium M processor, which is noted by it's clockspeed. It will work perfectly fine for most any application, short of gaming, which isn't a laptops primary use anyway.
This was not an attempt to correct you kg, I was merely trying to clarify the point you brought up.
