[Q]: Trackball feels as though its running with occasional grains of sand. Esc Key needed to \"get things going\" on first use. Key 7 fell out and seems to be partially broken as it won't clip back in as securely as the other keys. Rubber trim and foot fell off. This keyboard is slowly coming apart
[A]: Negative Review

[Q]: Great sound, great speakers.
[A]: Positive Review

[Q]: I received my Asus yesterday, I have been using it since. I had read the reviews and done my research before buying this product. I have to say, so far there isn't anything I don't like. The cons for most would be the power cord but I don't mind it too much. The battery power is great. It definitely lasts a lot longer then my laptop I sold to buy in its place. It fits in my purse and perfect to whip out and use anywhere in a wifi area or hotspot. The one thing I dislike so far is the fingerprints left on the screen when it sleeps. The picture is beautiful and the keyboard is something I'm still getting used to but some great things take time. This tablet is quite fast and for over all results, I'm truly glad that I bought this in place of my laptop. I am one happy customer with Amazon. They have always had the best prices and is always on time for delivery.
