Some of the models below seems to tilt toward gaming, but the GPU is useful if your engineering software utilise CUDA or if you do any 3D modelling.

How many USB3 port does Acer V7-582PG-74508G52k has?

iinm, 1.
It's skinny and don't have many port, only HDMI, 2 USB2.0. Weight ~ 2.2kg.

VivoBook S400CA-CA006H, i5-3317U + Intel HD4000 + 24GB mSATA + 500GB + (1366x768; touch)@RM2299[2kg], 4GB, W8

Not sure if Asus Malaysia release an i7 spec (btw i7 ULV is only duo core) S400CA 
Anyway, the S400CA listed above is very similar to the S300CA listed earlier, only slightly bigger and heavier. It has a small mSATA SSD for caching, which will improve responsiveness a bit, but it's a hit or miss affair.
Personally, unless you really need the big storage all the time, my suggestion for any laptop is to go full SSD if budget allowed (i.e. if laptop come spec with HDD, just grab a SATA SSD aftermarket (256G ~ RM600) and swap out the HDD (normally will not void laptop hardware warranty) to keep as external storage). Reduce weight, improve thermal profile, improve battery running time, improve responsiveness substantially, ....

Errr ..., you want touchscreen? 

Generally, if you really like touchscreen, please make sure you are totally confident in the strength of the hinge (part holding the screen with the base) for traditional laptop form factor. Nothing more annoying than wobbling screen (That's also why, if the construction is the same, smaller screen size may be more viable for long term abuse as the screen is lighter and won't strain the hinge as much).

I am looking for an ultrabook for my daily usage. Use it for daily work and may run 2 vm with it. Require VGA to connect to projector for presentation. Possible to have 0% installment for 24 months.

1. Preferred Brand: No preferred brand, but definitely no Acer
2. Budget: 5k
3. Usage: Daily office work, virtualization, visio
4. Preferred laptop/screen size: 13"
5. Prefer ultrabook, Gigabit LAN, VGA and HDMI

1. Preferred Brand : toshiba,acer,dell,asus..
2. Budget : below rm3000
3. Usage : studying civil engineering(not sure any high performance software needed or not), gaming such as Call Of Duty and GTA
4. Preferred laptop/screen size : 14

Additional Feature : 1. long battery life
                            2. good after sales service

I recently found a laptop Inspiron 14r with

-4th Generation Intel® Core™ i7-4500U processor (4M Cache, 1.8 GHz, GT750M 2GB)
RM2699 - 1 year warranty.

Adding up three year warranty , the price might shoot up to Y410p price.

Between the dell and lenovo , which tn screen is consider better?

TN screen in the Dell will be better. i tried using Dell and Lenovo, and the colours on the Dell's screen is very real life like.

too general if doing verdict like that=)

Looks like my option only left Asus and MSI since Acer only has 1 USB3 port and Lenovo's battery life is terrible. How is the battery life for Asus and MSI? I'm expecting a battery life of at least 4/5 hours.
