[ltp] T42P or Newer model?

[linux-thinkpad@linux-thinkpad.org]

Hello All,

Am looking at a full fledged T42P (1GB RAM/1.X GHz 
CPU/gigE/Fingerprint/a-b-c wireless/60G@7200 RPM etc) and a newer
T series models T60P. Which will be the next system?  Coming from my 
trusty T30, both are generation(s) ahead.

Are the newer models substantially (T60P) better than the 
tried/true/debugged units (T42P)?

Am leaning towards the tried / true model, but willing to listen.

Thanks in advance!

John
