Truly great minds might spot that a 1st-generation 330M isn't a second-generation 2330M.
Even greater minds would put forward that friend is probably looking at "budget" laptops.... hence processors inside will be a much of muchness, either old tech, or yesterday's new tech....
Groundbased apologies in advance if I'm mistaken... either way, I'd say "core" is the way to go, rather than "pentium".
