You have to fork out ~Rm250 to make it international warranty though..
You might want to omit the Haswell processor, then there'll be slightly more options

Buy when you need, wait if you can.

If you can wait, then there will probably be more options later on with Haswell

Netbooks are always best for seeding/torrenting lol, eco friendly

Cheapest 15" MBP also need RM5.5k ar bro

What is NAS?

Updated, thanks guys

Nah, I don't know much about computers to be honest
Technology is too fast already

They are different products.
Although both are G-series (gaming), one is 14" in size, the other one 15.6"

PM devour, storm88 or hikari85 for more details

We don't really have a lot of Haswell-powered, higher end ultrabooks at the moment

Best bang for buck

You don't really get that much a performance gain or battery savings for the Haswell processors (when compared to the 3rd), not for these power hungry i7 processors

Yeah, gaming performance depends much on the graphic card anyway, so gaming performance would be more or less similar. However, do take note that Y510p comes with Nvidia Optimus, so you will get slightly more battery life, if tis important to you
You can always downgrade, but its not really advisable as you might have problems finding drivers now, especially for newer laptop models.
And yes, you can swap the HDD with another faster HDD, or even SSD

He did mentioned he doesn't want Apple la bro
Newer generation ultrabooks will come eventually, although current ones are actually quite very capable of handling normal, everyday tasks ~

If you can wait, the upcoming XPS13 will probably be the closest contender to the MBA13, as usual haha

Not sure what's the main reason for the slow in terms of update... maybe they are releasing batch by batch, targeting budget consumer units 1st

Any links to back this up?

Not really sure its related to the "slow-ness" in the release of Haswell-powered ultrabooks
Based on what I've read, Haswell was actually introduced to reduce the steady decline in demand for notebooks as a result of smaller tablets/smartphones

walao, no one slept yesterday?

Yeah, RAM and HDD can be upgraded
