    i think I know the answer to this but is it pretty much impossible to find a 15" laptop that has battery life greater than 3hrs?

    It's highly possible. My T500 gets up to 7-8 hours.

    Maybe it depends on the hardware you're packing. I'm pretty sure there are no 15" w/ i7 and 256-bit GPU that has more than 3 hours...

    Duration of battery life depends highly on the screen size : cpu power consumption : hardware configuration : task execution : user habit ratio. Sounds complex right?

    You have only listed one element, which is the screen size. But that may not mean low battery operating duration if you had initially chosen low power consuming cpu, such as Intel's C2D or AMD Turion which consumes as low as 35watt TDP, partnered with 6 cell batt or more, integrated graphics, wireless off or on with just general web browsing, as well as low brightness viewing you could easily achieve more than 3hrs.
    (like mine when i got my Inspiron1501, Turion TL-50, 15.4inch, 6 cell batt, screen brightness tone down to 25% when doing web browsing, gives me 210mins achievement)

    My HP mobile workstation, Pentium M Based, 15.4inch 1920x1200 screen, with a dated FireGL graphics card and 7200rpm HDD, all are dated and power hungry, Still manage to get 4 hours on my battery (still hold a 100% charge) and ive seen some Pentium 4 Laptops (before Pentium M) that could get 3 hours.

    But it depends purely on what your doing, the power turns on, the capacity of the battery, the number of cells, and the power efficiency of the laptop and the OS, my poor old Asus S96S could only manage a mear 2hrs on a 6-cell 4400, where my friends similarly spec HP got 4hrs same size battery, same OS, and everything
