I have been offered a choice of 2 2nd laptops nice and cheap from a family friend. The laptops in question are a Compaq Evo 610c and 620c. I have checked the specs on the Compaq/HP website and the primary difference between the two is the processor. The n610c comes with a Pentium 4-M processor and the n620c with a Pentium M. I don't know the speed of the processors, but am I right in thinking that the Pentium M is the superior of the two? Thanks in advance for any advice given.
