(NOTE: UPDATED AFTER A MONTH OF USE) This review compares the Asus Cube to the Vizio Co-Star. I've been a Co-Star user for several months and had the Cube for about a month now. . I bought the Cube hoping it was an upgrade and would overcome my minor frustrations with the Co-Star (freezing up several times a week and somewhat slugish). Here is my experience: - The Cube isn't an upgrade for the Co-Star. Its overall performance is very similar. It's not slow, but you do have to be patient. And it still has quirks. Overall, it doesn't operate smoothly like a true, solid consumer device. - Both use the same Marvel 1500 processor. I think that is root of the problem. Until a device with an upgraded processor comes out, the GTV STB's aren't ready for mass consumption and are more of a hobby device. They are just too fussy. - Several others have pointed out the Cube remote has two design flaws. The buttons on the side are VERY EASY to accidentally push, especially when picking up the remote. It is a major pain! And the blending of the touch pad with the D-controller was not a wise choice. You have to be very conscious of how you are pressing the controller. Even after 3 days of heavy use I find myself having to actually look at the controller to avoid hitting "OK" instead of "UP". UPDATE: a month later, same opinion. Fewer accidental selections, but only because I've grown so deliberate in using the remote. - As discussed by others, out of the box, the IR control situation on the Cube is a problem and doesn't provide enough control options. To solve the IR control situation you need to get a dual or tri- IR blaster, as noted by the poster below. It's only a few bucks and totally solves the problem, giving the Cube a big edge over the Co-Star. Still, the Cube should have shipped with at least a dual blaster - most people these days have at least a STB and TV to control. Also, the wording of the IR setup is not clear and led at least me to believe that the IR would control either the STV, TV or AVR, not all of them simultaneously. - The Cube interface is "cool" but not helpful and at least for me annoying. - Just like my Co-Star, I was having issues with the device failing to shut down properly and getting hung-up/freezing, which results in a need to unplug every 3-4 occasions of use. I now believe that it's not the Cube, it's the Open Launcher app that appears to make my Cube unstable - occasionally failing to shut down and needing to be rebooted. I've made the app developer aware, but a fix isn't on the immediate horizon. Using just the Cube Launcher, my system is much more stable. - Voice Search as integrated into the remote is great. It's substantially better than having to use EasyRemote or the GTV remote on your phone. So as much as I was hoping for a GTV upgrade, the Cube isn't it. I'm hoping for something better as the year progresses.
