Whats the T and P all about?

seems to me that the T9xxx are 35watt and P9xxx are 25watt

anyone know if this equates to worse/better performance and increased/decreased battery life?

Intel usually list the specs & features on their website, checked there?

yea, but i doesnt have performance,

I was hopeing someone with experience with both types might know something

Im trying to decide what will be best for the new laptop and the p8700 is looking good for power usage
