Hey guys

1.Brand
A reliable brand (good customer service , and possibly user friendly)

2.Budget
Budget would be around 3-3.5k , 4k can also

3.Specs
Im looking for a laptop which can last for 5 years
Can handle engineering programs like Autocad and the like
battery life more than 6 hours if possible


4.Size
I dont mind if the screen size is small , as long as it shows the information thats there im fine
the laptop should be light and portable enough to carry around college or uni


additional info :
1. im starting college soon and my course requires me to complete a large number of assignments

2.im also flying off next year , so to make it easier to contact families and friends , ill be getting skype . so i think it would be good if the laptop had a built in webcam and came with a headset

3.im a light-medium gamer , the only game i'll play on the laptop would be football manager and maybe a few old games like company of heroes or left for dead

4.im not really computer savvy so if possible im trying to find a laptop which if possible has a 0% chance of getting viruses and does not have many technical problems . for example my sisters compaq's battery pack is already dead and she has to rely on the plug to keep it on

5.ive done my homework and people mainly recommended the thinkpad series , macbook pro and the dell latitude series. among these which is the best value ?

6.which companies have very good customer service in canada , because ill be heading there next year .

and i need you guys to clarify this thing for me

i heard ASUS laptops are good but they easily have problems with the specs and stuff which turns me off getting them .is this true in any sense ?

Budget= RM 3K

Characteristics
good battery life , i.e can last 4.5 hours

a little gaming
ill only be playing football manager and company of heroes
since these games are quite old already , i expect them to run smoothly (<40fps) around mid-high setting

media
if possible got nice webcam and headset so can skype easily

light enough to carry around college (2-2.4kg)

i have no preference on screen size whether its 13 , 14 or 15 inches

so far i have done my research
and i have narrowed down to

Lenovo Y460

ASUS UL80VT

ASUS U30Jc-A1

also i need some opinions about the ASUS A42Jv because theres no reviews i can read from the net

id like to know for the A42Jv
how long is the battery life
specs
and how well it fits to the characteristics as above

thanks guys
