guys, i'm going to buy a new laptop soon, and i've got 3 choices based on the bits of info that i got just a while ago:

1)Dell Inspiron 14
-CPU: intel core i3-5005U 2.0GHz
-500GB sata HDD
-2GB nvidia graphic card 920M
-1 year warranty

2)Dell Inspiron 3421
-intel celeron ®1017U 1.60GHz
-1TB sata HDD

3)NB ACER AS ES-473
-intel celeron 3215U 1.70GHz
-4GB DDR 3 RAM
-500GB sata HDD

P/S: i'm going 2 study computer science in uni, so, i need a laptop that able to ensure that my software is smooth when i run them because sometimes i will run 2 IDE's at the same time. as for the weight/portability, i don't really mind that much, and oh, i don't really play games that have very high requirements

and also, i'd like to know which one of these laptop is flexible and can be replaceable... because i intent to replace my hard disk to SSD in near future, so yeah, if i could, i wanna avoid any laptop that has most of it's hardware soldered/fixed in it..

yup, very very tight...

if budget not an issue, i've already will go for higher CPU specs etc...now i'm a beggar lol..

my Asus X451CA failed me, and yeah these 3 are my only choices after lots of narrowing down..
