I think Praz is pointing the right way. I think Intel has been so fixated on minor improvements and power savings (with little regard for quality control) that things have gotten really difficult for mfg to manage. I have used boards from 3 of the major mfg and each has their own quirks. ASUS seems to have the least - or at least most manageable - issues. Always need to remember building your own system isn't plug and play. You need to know what you are doing, aim within reason, manage expectations, and have a little luck. If you want plug and play stupid easy (with way less functionality) there are iPads and ZenPads.
you would expect them to work perfectly together. Or is that somehow expecting too much??
