both of you go get Lenovo Ideapad Y580, i7-3630QM + Nvidia GTX660M + 1920x1080 @RM2999[JBL], 4GB, 500GB(5400rpm), W7HB/W8, backlit keyboard, 2 yrs warranty

Its the best you can get for under Rm3k
The HDD runs a bit slower than your A52j, and runs abit hot.. but easily rectifiable by upgrading to SSD (when you have the budget later on) 

7200rpm HDD is slightly faster than 5400rpm HDD, it will impact any disc accessing activities (OS boot, program launch, swap file, ... )

SSD - solid state drive, inside is NAND flash. Relatively expensive (128G ~ RM250+). Compare to HDD:
run (very much) faster
quieter (no moving parts)
cooler (generate a lot less heat)
help laptop getting better battery performance (use less power)

All the high end ultrabook use full SSD.

Lenovo keyboard is good. The touchpad in Y580 is up to personal taste (you go and try it to find out).

Dust? Blow them away (seriously, use compressed air or brush)

Important to keep laptop clean. You do heard about the research which found keyboard is dirtier than toilet seat?
