I got one that was an "open box" item and the volume stopped working - the buttons and even settings wouldn't change the volume which had been set to the lowest setting (mute).  I tried turning off but then it didn't turn back on.  Took it back and it was replaced with a brand new one!Now I've had it for a while and have 3 accounts setup, one for myself, one for the wife and one restricted account for my 5 yr old.  The wife mainly watches videos (YouTube), son plays games and I play and surf.  Response is great although our internet connection is at tops 6Mbs so there are times when something that needs internet access may lag a bit.  I noticed one app that I play on my HTC One S always complains about the connection when I use the HTC phone, but on this tablet it just runs smoothly without every complaining - odd since they use the same WiFi connection.  The tablet response is good.The Android OS on this tablet is simple compared to my phone which has the HTC Sense version - not that the phone is "hard", but it may be why the phone seems a lot less responsive than this tablet.If you used any of the other OS (iOS, Win8, Firefox, etc...) then you will find the controls somewhat familiar.  Although there will be differences, they won't keep you from using the tablet.  You still have the apps you can download - some are free and some are paid apps.The volume control issue on the initial tablet seems to happen a bit as this one did the same, but I found out I could just change user accounts and it will work again - odd, but hopefully there will be an update that will prevent that from happening at all.Overall I am happy with the purchase and although there are a few things I wish it had (like expandable memory slot for a SD card for one, HDMI output for another), I think it's a great, fast and nice size for our first tablet.Update: Still have issue with "mute" getting stuck and having to swap accounts to get audio volume to function again.  But now also have an issue where the notification pull down bar (or whatever you want to call it) appears as we try to launch apps, swipe, or do anything.  We are having to power off and back on before it will work again.  Whatever they did with the latest release appears to have made the tablet worst than better and I've adjusted my rating accordingly.Update2: With the install of 4.4 KitKat, the screen problems appear to be gone now.  I haven't been using Mute a lot lately so not sure if that issue is also gone.Update3: And the problem is back!  Put a video on YouTube title Ematic vs Nexus 7.  The Ematic is a quad-core for $80 and in my opinion a better buy since it works (at least for now).  I'm going to see if Asus will take their paper weight back and give a refund.  This would be great if it worked correctly.Update4: Tablet's been with Asus for over two weeks.  RMA says waiting for customer confirmation "swap" so I called to find out what that meant and was told I will receive an email when Asus decides what to offer me.  Not a good experience at all.  You take a chance with these tablets that they will not work and you'll be stuck paying to send them back to Asus and wait for them to decide "what to offer you".Update4.1: May 30th received the replacement.  Asus sent a notice saying they shipped it and to check the "courier" site for updates but only listed "TRUCKING" as the courier with no tracking info.  On May 29th Fed Ex left a message saying they will be delivering a package that required a signature - that would have been hard to arrange if we were in a situation where no one would be home.  The item shipped from CA and not TX so I figured it must be a replacement unit and I was right as the serial # is different.  So far the replacement seems to be working. 

Question: What is your feeling?
