New office work laptop help pls

Hey guys id really like ur help in this..i need a new laptop for work..so here s what i want it to be..pls try and give me many different laptops   thank you all

budget: up to 1100$

screen size: ideally 15.4"

HDD around 200-320 GB

portable laptop not desktop replacement since i ll be taking it every day from home to work

mainly used for web browsing, video viewing, documents viewing and editing..the basic corporate stuff but id like it to be fast because im a bit impatient :S

would not want it to be acer, i had bad reviews about it from friends (in terms of longevity)

battery time around 5 hours

time before buying new one about 2-2.5 years

might occasionally be playing DoTA on high settings but that shouldnt be so hard

and i think thats about it   so if there is any information missing ask me please  

waiting for your most helpful replies

thanks guys
