I own a Transformer Prime. It's thirteen months old. Based on my experience with Asus, its product and complete lack of customer service, I will NEVER buy another Asus product. I say this sadly, because when I first received my Prime, I loved it, and bought one for my wife and another Asus model tablet for my daughter a few months later. However, after 13 months, the bloom is definitely off the rose. Since I've had my tablet, I had to RMA it when the screen started "bleeding." Asus lost my tablet and for a month couldn't tell me where it was, until it was miraculously "found" and returned to me via the cheapest and slowest shipment method possible. Since that time, the hdmi port has stopped working and recently, the camera stopped working as well. When I contacted Asus, they just blew me off, since it has been 13 months since I purchased the device, and the warranty expired last month. Also, the broken and frequently-nonsensical English contained in customer support emails and on the Asus website are a nice touch as well.
In an nutshell, if you haven't bought an Asus product, don't make the same mistake I did - DON'T BUY ONE.
