For those looking DFO unit, public now can direct buy online those DFO unit.
There is direct link but not available on hand now to share

Yup, 8gb only.
The 4K about 3 hour different in battery life base on review

If you professional photographer who edit Premier Pro + Lightroom together, then may not sufficient...

If only occasional user like me, 8gb is good enough for lightroom alone

nowadays 8gb like basic de... u can't hv smooth game with 8gb.. haoh

I own a first gen XPS 13. 8GB RAM, 5th gen i7, 256GB SSD. 4 years old, going on to 5 years now.

Still works like a charm. Even after all the abuse i put it through. Only issue I had was the battery (cause of the abuse), but that can be changed I guess. After changing I was getting like 8 - 10+ hours battery life again.

I use it mainly for browsing internet, FB, Youtube, watching movies, Spotify, etc. I also occasionally do some light gaming like CS GO (with lower graphics), Starcraft 2, FM 2018, etc. So far, OK lar, this lappie not meant for gamer or hardcore workstation stuff, but it gets the basics done and done very well.
I thought all FHD versions are matte? I remember the glossy screens are touch screen models which are all QHD models.

Mine is FHD.. i did not take 4K cos I need longer battery
I don’t like bring power cable when going out coffee shop..
I only bring one power bank..
I scare 4K drain too much battery and my power bank might not last me for a day when I outing

I search review in YouTube before, I heard from YouTube say they discontinue matte FHD.
They use glossy FHD with some matte coating at outer layer..
It was not that glossy as previous 4K model.

Haha, you just got to know what you want and discipline to take care of the laptop lar. To be honest, go to a showroom and try out the laptop yourself. Look at it, touch it, use it, carry it. That's the most important thing. One thing to note. There is a bit of fan noise, when you max out the processor (which isn't often for me), btw, but since I use earphones all the time, I rarely notice. Some people find it a deal breaker though.

As for gaming, actually it is better not to go for 4K cause that is even more demanding on the graphics which is already limited in an ultrabook form factor. Better to stick to FHD.

basically now day all accessories should hv USB-C
USB C external drive, USB C LCD monitor, USB C to HDMI monitor, USB C external DVD Drive, USB C pen drive, USB C phone cable for android and iOS and many more..
all already available... just you need change new cable or get new stuff. no need dongle if you only hv 1 usb C like macbook 12.
basically last me over 12-14 hours base on normal surfing, youtubing and excel..
if on gaming, and full power, only last 4-5 hours 

Haven't seen a good wireless mouse with USB-C interface yet (unless BT), bro! There are a few on eBay and Amazon but quality is so-so. Of course the other
way is to get a good all-in-one USB-C hub like the Dell DA300 and be done with it la ...

new? claim warranty

The backlit is not one light per key like MacBook
Thus you will feel the key is not properly light up.

chrome eat ram

Oh, you're in Penang. I guess not all PC/IT shops will stock up on an XPS for demo unit.   

All the best. It should be fine lar. Enjoy your new toy. 
I use Opera. 

But browsers these days eat RAM a lot lar.

Firefox better for low ram things.. i use 32gb so i chrome multitab.. haha
