Preferred Brand | Acer or Asus, but I'm open to suggestions from other brands too

Budget | RM 2k - 3k

Usage | Main laptop for college as well as serious media usage [Internet, videos, music, word processing, graphic design, photo editing, etc., etc.]

Preferred laptop/screen size | 14"

I'm upgrading from a 4-year-old Acer Aspire 4930 [14", 2GB RAM, 250GB HDD, Intel Core2 Duo P7350 (2.0GHz)] so I'm looking out for these specs:

+ Intel i5-2450M (2.5GHz)
+ dedicated graphics memory (1GB/2GB) alongside 4GB RAM
+ optical drive
+ long battery life
+ HDD space (500GB, perhaps?)

Please and thank you!
