So far almost 2 months with the SP4 and I'm now very satisfied. Albeit the big hiccup at the start which required me to send in for a replacement and getting a refurbished, but at least it looks almost new.

Performance wise I feel still below my previous rMBP 13" 2015, but only just. But the portability and functionality is a major plus. Tablet mode still sorely lacking in the apps department, but I got this solely as a laptop/desktop replacement.

Especially stoked bringing it on my overseas trip and being able to play around with Photoshop/Lightroom after a day's worth of photo shooting. Also using the pen for masking/layering gives an even better sense of control, can't think of any other portable hybrid that pairs so well for avid photographers

And light gaming e.g. Dota, FM2016 also performs well and smooth. A very well versatile all rounder.
If there is a feature I'd like them to add for the next SP5, it'll be a USB-C port which can be used for charging as well. It'll be nice to use normal powerbanks to charge otg.
And a magnetic rechargeable pen instead for convenience sake (though indication from news is pointing that this feature will be added in SP5)

Windows 10 as an OS has been improving, though I still prefer OSX for its simplicity and stability.
Especially a time when 150+ GB mysteriously got used up. That was a really fked up Win 10 system.

S3 uses a proprietary magnetic USB cable that plugs into the power supply? SP4's magnetic cable is fixed to the power supply.

How fast it charges with powerbank?

I chatted with Lazada. They confirmed the following:
- Official MS product and warranty (but only 6 months).
- Brand new unit

So, this is a real good deal. 

Ya lol. Been using Windows my whole life, so just more comfortable with it.

And where can I find a shop that sell surface pro 3 here? Bcs the weird thing I just check many online website like lazada and Harvey Norman and they only sell surface 3 and surface pro 4, I don't see them selling surface pro 3 anymore???how come

Thanks for replying. But this model don't have any graphic card? Will this be an issue?

Oh wait. it seems mrl is correct. Surface 3 does run full Windows 8.1. I always thought it's an upgrade of Surface 2 running WinRT.

Seems strange then for MS to roll out both Surface 3 and Surface Pro 3 if both can do full Windows.

Learn my lesson the hard way when I bought HP Elite X2. Cannot be charged and because it is a compact computer everything is integrated and I have to change the motherboard which would cost me more than a new laptop (about RM3k plus). I bought the HP less than two years for RM5k. But the warranty had expired. Now, when I bought the new Surface Go I took the five years warranty. So sad, I cannot repair the HP just because the power charge was broken.
