T7500 is a little faster but the difference isn't much,if u care about battery life then go for T8100,it has better battery life (because its a 45nm CPU)

The performance difference will actually be pretty negligible. Clock for clock the Penryns are a little faster due to new enhancements, so the 100mhz difference won't be much of a difference at all. I agree about the battery life though.
I have a T8100, my cousin has a T7500. He has an HP with an 8600m gt with extended battery, me a sager with an 8800m gtx, so battery life is kinda hard to compare - however, in cpu tasks, both of them finish pretty much on par with each other.
