    I don't think it will hold you back noticeably @thundercracker. ZBrush doesn't even rely on the GPU at all.

    Yeah I just realized my desktop GPU has 2gb of vram, a gtx 760, and I've never been shut out of any 3d apps. That ebates deal seems to last for the week I think; maybe i'll hold out and see if they drop the 4gb model. Sucks playing the guessing game.

    That is good news and bad news. Good news that the 1050 4GB is on the way, but bad news that it's unclear when it'll be available. I wish Lenovo were more specific. I'm running out of time to order this machine. I want it for a trip that's a month and a half away now.

    Today's sales really complicate things. Lenovo is selling the 1TB model for $1500 (regular $1650). It's only got the 1050 2GB though. Debating on buying this or waiting a bit longer for the 1050 4GB. I'm leaning towards waiting for the 1050 4GB as I run some VRAM-intensive apps. This machine will be a desktop replacement for when I'm away on trips or don't feel like sitting at my desk.

    I don't think that ZBrush, Blender, Maya, or other 3D apps will have trouble with 2GB. 3D SDKs such as Unreal or Unity and some games such as Planet Coaster and Witcher 3 are likely to perform significantly better on the 4GB.

    Considering it's a thunderbolt 3 with 2 lanes, what can it do that a USB C 3.1 can't do?

    Couple of things. It supports 4K displays and other Thunderbolt devices which USB 3.1 doesn't. Its throughput is still double that of USB 3.1 Gen 2. So it's still better, especially if you're planning on using Thunderbolt displays.

    Considering it is only 20 GP\s, how is it different from Thunderbolt 2 for example?

    From a PCIe perspective, it's the same, but there are specs that are supported by version 3 that aren't supported by 2: PCIe 3.0, HDMI 2.0, DisplayPort 1.2, and USB-PD.

    Also, USB-C dongles are far more common than Thunderbolt 2 dongles.

    Couldn't help myself, got the Yoga 720 15 4K 16GB RAM 512GB SSD 4GB GPU RAM.

    Here are my first-impressions:

    The negatives, in no particular order:

    Ports:
    • No Ethernet, HDMI/DVI, SD card reader, smartcard, LTE
    • Only one USB 3.0 port at each side
    • Only one Thunderbolt 3 port, with 2 PCIe lanes (not 4)
    • All of the above mean dongles! Dongles for everything!
    Build:
    • Keyboard layout doesn't take advantage of its size. Half-size arrow keys, no right Windows key.
    • Yoga fold form-factor means keyboard is exposed when in tablet mode.
    • The chassis is metal, but the coat of paint makes it look like plastic.
    • The trackpad is plastic, not glass.
    • Power adapter is gigantic.
    Display:
    • Either the digitizer or some sort of coating leaves a grid pattern on the display. At first I thought it's dithering, but that doesn't appear to be the case. Only visible when almost pressing your face to the display.
    • Display doesn't arrive calibrated.
    Software:
    • Loaded with Intel and Lenovo bloatware.
    • Comes with Windows 10 Home edition, not Pro. I guess Lenovo doesn't consider this a business device.
    • Preconfigured Lenovo partition takes up 25 GB for no reason at all.
    The positives, in no particular order:

    Thermals:
    • Haven't noticed any throttling. The device does run hot to the touch.
    • The fans are quiet, even when they ramp up they're low-pitched like they should be, not annoying.
    Display:
    • 15.6" 3840x2160 gives ample work area
    • The Wacom AES pen (Bamboo Smart 2-in-1) works great, there is little to no discernible gap between the pen tip and the cursor. There is slight wobble on slow lines. Not as good as EMR, but very nice to use.
    • Bezels are relatively thin.
    • Brightness is good, haven't tried it in bright sunlight yet.

    Compared to my previous device, the Fujitsu T904:
    • Quiet fans are a blessing.
    • Chassis finish does not feel as premium. I want brushed metal palm rests, glass trackpad!
    • Keyboard is much nicer, gives more resistance, key presses give more feedback.
    • Fingerprint sensor is better.
    • Higher res and bigger display gives more room to work. Bigger and heavier, that's the price for more space.
    • i7-7700HQ means I can ditch the desktop
    • Gonna miss the ink precision of EMR
    • Not gonna miss the gigantic air gap between the pen tip and the display
    • Won't be using the Nvidia GPU, would have preferred 4 PCIe lanes instead.
    • Gonna miss Ethernet port, full-sized SD slot, smartcard slot, HDMI port, LTE
    • Finally, SPEAKERS THAT REACH A HIGH VOLUME.

    What country do live in that you got the 4gb Vram?
