I have run Origin 9 SR0 64bit on Surface Pro and did not see any problems.
Compared to my Windows 7, 2.8GHz Core i5-2300 CPU with 6GB RAM and NVIDIA GeForce 8600 GT video card (OpenGL version 3.3.0) This Windows 8, 1.7 GHz Core i5-3317U CPU with 4GB RAM and Intel HD Graphics 4000 on-board video (OpenGL version 4.0.0) feels slower than either clock speed or OpenGL version would indicate.
I tested number crunching and graph production with: // BEGIN sec; col(1)=data(0,2,.000001); col(2)=3.3*sin(1000*pi*col(1))-2.2*cos(500*pi*col(1)); fft1 2; watch; // END and got about 38 seconds on my desktop and 56 seconds on the Surface Pro.
The OpenGL version on the Surface should support anything we throw at it and the 1920 by 1080 display is very crisp, but the OpenGL performance (speed of display and rotation) of the Intel chip is not as good as my graphics card.
While I did not have Office installed to test OLE, I could paste an Origin Graph in Wordpad and double-click to edit in Origin (Origin as Server) and I could add a Paint object to an Origin Graph (Origin as Client) so OLE seems fine.
Origin's usefulness in a touch environment is limited. It does not respond to the standard touch and hold to bring up (right-click) context menus. Since Origin makes extensive use of right-click context menus (and some features may only be accessed that way) I definitely would not want to forget my external mouse if I left my keyboard at home. The on-screen keyboard appears to be missing both the Alt and Windows keys.
Thanks for taking the time to do that. It would probably make a huge amount of sense to wait for the second gen to actually get one (while researching keyboards w/ trackpads).
But to put things in perspective...
I ran that script on my MacBook (2.26 GHz Intel Core 2 Duo, 4 GB memory) running Windows7/OriginPro under VMWare Fusion 5.0.3 (using only 1 core and 2 GB mem). It took a whopping 415 seconds!
