Good question. I've got a Lenovo Yoga 2 11 with much better specs (Pentium, 4GB RAM, 500GB HD, etc.) and it barely puts along on Windows 8.1. And every week or so you turn it on to see the dreaded, "You've got 9,347,824 updates ready to install. Would you like to install now and hopefully live long enough for Windows to finish?" I'm thinking those Streams will be slow-motion machines!
