Hi, please recommend me a laptop that is below 3k.

Brand: Asus, Dell... doesn't matter as long as reliable and robust.
Size: 14 / 15 inch
Price: Sub 3k
Spec:
--------------------

Usage: A lot of reading journal + doing programming in Visual Studio 2010 & Ms SQL 2008.

Proc: Probably i5 with turbo boost. <--- VS2010 is a b**** on my old Acer 4530 (Turion dual core 2 GHz).
RAM: 4GB ram at least.
Keyboard: Backlitted keyboard. <-- work on bed, light off.
Battery: Long battery life (no need discrete graphic card). <--- most important
HDD : size doesn't matter.

Additional note: I have a PC for gaming, multimedia and other heavy stuff. For laptop, the heaviest will be Visual Studio + Ms SQL 2008 express. I need this laptop for work and research purpose.

Please advise. Thanks.
