Macbook pro 13 or hp envy 14?

I need a notebook with awesome battery backup time for my astronomical observation sessions. In which i need atleast a battery backup of about 6hrs. I know that i can install windows xp or 7 on macbook pro 13 via boot camp but still i want to ask if envy 14 will be able keep it up with the battery backup of macbook pro 13? Also are envy 14's speakers better or at par with macbook pro 13? The price shouldn't go above 1200$.Macbook pro 13 or hp envy 14?
The HP Envy if you are looking for more stuff for your money...



And



The Macbook if you are looking for the Mac OS...



Generally Apple products are a bit more expensive than other products... (especially laptops)





I reccomend the HP envy as you can customize it to fit your needs-

as for battery life, you can always purchase extra batteries, HP features oversized batteries, in the ENVY's case it has a stndard of an 8cell- arround 5-6 hours, depends on what you use....
