Overall a good product, but it has some issues.My first try using it resulted in a blue screen of death.  A few tries later, I got it running off an HDMI monitor with a USB keyboard.  After about a million Windows updates, I was able to get it going on my TV.Using a 64Gb microSD card causes it to bluescreen on startup, but without it, everything is fine.Its not the fasting thing in the world, but it will easily run Netflix, Youtube, etc. without any problems.  I wouldn't try it for gaming.Amazingly, it runs just fine using the USB on my TV for power.  No need (at least on my tv) to plug it into an AC outlet.Pros:  Runs Office, Chrome, Netflix, and all the basic pc stuff perfectly  Can be powered from TV USB  Full version of Windows 8.1 and its activatedCon:  Unstable with my MicroSD card.  Have to run it without one.Very happy with it overall.  Would have given if 5 stars if the SD card was stable.New Information and a Warning:After random BSODs on startup, even without an SD card, I tracked down the problem to the Vizio TV I was hooking it up to.  Apparently, Vizio and Intel Compute Sticks do not work well together.  The issue is the sound.  If you disable the sound, and it starts up fine.  Sound on and its a coin toss.  Not sure if this is all VIZO tvs, but it is on mine and I have found many people having the same issue.
