Not the OP, and sorry to resurrect a thread, but I'm considering something similar, only a 2420 instead of a 2410. Per the manual, the 2420 supports:
• Intel® Celeron® M processor 370/380/390 (1 MB L2
cache, 1.50/1.60/1.70 GHz, 400 MHz FSB) or higher
• Intel® Pentium® M processor 725 (2 MB L2 cache, 1.60
GHz, 400 MHz FSB) or higher
• Mobile Intel® 910GML Express chipset
Why do you say there won't be much of a difference?
Since they say "or higher", would it be plausible to use a Pentium M 755 (2.00GHz, 400MHz FSB)? Would that change your answer above?
Of course, with a price tag about $100, I'm not sure it makes economic sense to do it. I already have 2GB RAM.
A Pentium M would give better performance than a Celeron M. By a lot. I know from experience.
My fiance had a eMachine with a 2.7GHz Celeron. I upgraded it to a 2.8GHz Pentium 4. Only 100MHz more but the Pentium 4 made her system boot up probably 3x faster, although it was still crap compared to my 3.4GHz P4.
Celeron is always the low end brand. Its just like Sempron. Lowest binned CPU.
