I probably should clarify. The parts of SAS in the EAS (Educational Analytic Suite) run on the S3 with Win 8.1 (not Pro or Enterprise). There are some parts of SAS that won't. I haven't tried Enterprise Guide but I don't think it will work. SAS Analytics (text/data mining) almost certainly won't work, the processor just isn't up to it. If you install Win 8.1 Enterprise or Pro, Enterprise Guide should work, but only the components of EAS will run in vanilla Win 8.1.
Another question: Do I plan to use it for travel. The Surface 3 is built to only work on WiFi channels 1 to 11. If you go to Europe or Asia routers may use channels 1 to 13. Your Surface can not see channels 12 or 13 and you will have no WiFi.
