In case of 4gb of ram can it be expanded?

I'm patiently waiting for the UX360UA, which is a higher end model that looks identical to UX360CA but comes with i5/i7 processor, backlit keyboard, 16GB ram, larger 57whr battery and an optional fingerprint scanner. Currently available competitors are Lenovo Yoga 900 13.3 and the HP Spectre x360 13.3. For me though, the yoga's lack of FHD option and lack of 16g ram option, and the spectre's weight, overheating issues, poor ergonomics and HP's quality control issues are all huge turn offs. My dream laptop is Thinkpad X1 Yoga from Lenovo that ships everything in lenovo plus an awesome thinkpad keyboard, 14' FHD anti glare matte display and SM951 pcie nvme ssd in a most portable 1.3kg form factor in the market. Unfortunately though, I can't afford this gorgeous US$2,400 machine so I've been patient waiting for the UX360UA. It'll probably retail for US$1,000~1,400 depending on its configuration. I must say I'm very excited!

The wifi doesn't work when something is plugged in the left usb port for me....anyone else? So strange. The right usb is totally fine.

They made a great laptop then put black keys on the keyboard and NO backlighting....that's right , no backlit keyboard. Try typing on a plane or in low light on that, believe me, I just got one and it is a misery.

Here's hoping for an updated version with Thunderbolt 3 and keyboard lighting :)

Price is ridiculous. It is interesting that Dell E7440with 4th gen Haswell 4600U (3.3 Turbo, 15Watt TDP listed, 17 W real after long time) draws (whole laptop) 2.5Watt with 8GB RAM and LCD on minimum.With LCD Off 1.1W.
