One question:
if you guys have an Dell XPS 13 right now, what would you do with it? Is there anything you would want to change (eg. hardware)? and what are your concerns.
Frankly speaking, I think i might give/sell it off to my brother-in-law who needs one for his work since he already intend to get one during upcoming SITEX (assuming if i get it). With it, he can port it around many different places to meet several clients without worrying battery going flat or feeling it burden with the all workday battery life (8-10 hours) and ultra lightweight. His clients will also feel more confidence investing in him seeing his unique foresight with the right choice of laptop, witnessing its ultra sharp and vibrant display, and that one-of-its-kind laptop screen bezel on the virtually borderless InfinityEdge display. With such laptop line popular as a expensive premium, his client will also think he is doing well in his career to have the ability to own such a premium gadget and hence have more faith in reaping better profits from the investments with him. Huat ah!
After reading reviews and opinions from the rest here, i would like my unit of Dell XPS 13 to have these improvements:
Screen
Given this laptop primarily targeted at business and design media professionals, the screen still fall short of colour calibration to moderate its rather cool default colour tone. It will have been truly ideal if Dell does factory colour calibration just like what Aftershock offers on the laptops before handling to end users. This will have really hit Apple in the nail to seal its lost against Dell XPS laptop in the war.
Better IGP
As mentioned by kimsix above, Iris Pro graphics is a better candidate to power such high resolution display for media productivity as well as some light gaming. Battery life on this XPS 13 is already pretty long, so trading off some for better gaming performance shouldn't see any objection from potential buyers.
Removable RAM
Yes i do see having totally 2x removable RAM slots as an achilles heel to the laptop's thickness. But Dell can have been more flexible to offer both soldered on RAM as well as a single SO-DIMM slot for expansionary purpose as well as mitigate the problem of spoilt RAM on the long run. Since they can afford to have M.2 slot and mPCIe slot, i really don't see why they can't have a single RAM slot of the same thickness.
Webcam
Shift its webcam to the centre zone, ideally just adjacent to the Dell logo to achieve a better view for the opposing viewer and for selfie shots. Intel Realsense 3D camera as an optional upgrade is also welcomed to value-add the experience on the laptop.
Gigabit Ethernet LAN port and SIM card slot
As pointed out by Ohayo!, omission of these ports are a big deal breaker for those business associate individuals or potential enterprise contract as a whole. Especially for LAN port, since it is one of the key necessity feature in corporate environment, where network security and stability is paramount. It is still possible to include the LAN port with an enlargeable port flap as seen in my earlier post. Having a SIM card slot also enable to fully maximise its lightweight advantage to connect to the web anywhere on-the-go, which is advantageous for them to monitor latest news / stock market realtime.
Hackintosh 
As mentioned earlier, Windows 10 and its programs still have a long way to refine and iron out to deliver a truly seamless high quality GUI. I would like the capability to turn it into a Hackintosh to take advantage of its high resolution friendly ecosystem.
