yeah... a lot of  variation of notebook.. and try get lower price as u can.. buy w/o free gift will reduce the price too. (laptop cleaner, free mouse, or watsoever its free) u dont need that dont u  i think all worth rm100+ but if u want other place also can.. its up to you. jz mke sure warranty issued by the manufacture itself.
Windows tablet?    i bet u need use freeDos and install ur own OS (win7ult)..  might be some Programming Language cant run properly in win8 and above.. some crash a lot too

yes you do not need powerful hardware.
in fact if you are in comp sci, you would learn to optimized your codes well enough to be below certain complexity.
as you are studying, the problems would not be complex at all.
other hardcore programming tasks (classification, machine learning etc) would not run on a laptop anymore (no matter how powerful your laptop is).

from my experience, get a mobile laptop with good battery life for quick coding etc (i am teaching CompSci in Monash) and if you can a SSD in it.

ps: get a dual core i5 for your processor, at least 8gb ram and a ssd
