It looks as thought the 2310 processor/computer is ~1/4 lb heavier and has 1/2 longer battery life "rating"...although the 380 processor that I have used doesn't have near the 5+ hours it is rated at...but i is a lot longer than past batteries I have had.
Out of curiosity, is the 380 "a lot" faster" than the 2310? It "sounds like it based on the 2.53 vs the 2.1Hz, but somewhere I read that the 2310 would be "faster" if they were the same speed. Given that they aren't the same speed.
I'm also curious why the "newer" one is slower then the older generation? Do you happen to know?
But what about the fact that the intel HD graphics 3000 (on the 2310m processor) performs better than the graphics on the 380m? Also, the 2310m results in better battery life. Would the 2310m + graphics 3000 combination result in better overall performance than the 380m + it's graphics?
AT least for me, an updated graphics package is not an issue, so it wouldn't be worth paying extra for. And quite honestly, the extra weight to lug around is not worth the very small increment in battery life.
Or, were you talking about there possibly being more than the 15% CPU adjustment that WR2 noted?
