The 15 inch Spectre X360 is (a bit) heavier than the 13, but the additional screen size is a plus when working on artwork/viewgraphs/decks etc. What surprised me was, that, the Adobe PS software had almost microscopic sized text/tools when viewed in the high resolution display of the Spectre X360 15 inch. I did not see this in other software that used the pen. The color and usable viewing angle of the display is remarkably good. The 15 has more I/O ports than the 13 and also a SD card slot which helps if you are working on photos from your digital camera. There is a Nvidia internal GPU card that is CUDA compatible so you could (theoretically) run deep learning algorithms on it (tensor flow etc.). Sound is good from internal speakers, with enough volume to enjoy YouTube University e-learning or just video. I enjoy running/viewing dreamscopeapp.com with the color fidelity.
Let me know what you think if you get one.
