I'm OK if i3 or i5 does the work equally well too.

Oh the video editing is kinda rare though, most of the time is photo editing so I need good resolution display.

I'm always travelling so 15" sounds heavy to me.

Well, unfortunately there's no high-resolution 14" for that price range, you'll just have to make do with the standard 1366x768
These 2 will be good:
13" Asus U31Sd, i5-2410M + Nvidia GT520M@RM2999
14" Asus U41Sv, i5-2410M + Nvidia GT540M@RM2899
Both have rather strong performance and battery life
If you want to save more money, then the:
Acer TimelineX 4830TG, i5-2410M + GT540M@RM2499
I know you don't want Acer but its has really improved over the years, and this one is simply too irresistible haha
Oh ya, it has long batter life as well~
