Have bought 2 asus devices. 1 was a laptop. Straight out of the box the USB ports were not working. Tracked it down to bad drivers for the USB 3.0 port. The work around was to disable the 3.0 drivers so at least the 2.0 ports would work. Then updated drivers came out. Still did not fix it. They shipped the laptop with bad drivers, yellow bangs in the device manager, and I had to troubleshoot the thing because the only thing support said was to restore it back to new even though it was broken new.
The second device I bought was the transformer prime. Bought it when it first came out. Specs said GPS. Metal body prevents the GPS from working. A couple weeks after I bought it, instead of coming up with a fix, they removed GPS from the specs. WiFi signal strength is also about half that of any other device in my home. Again the metal case messes it up. Then the final slap to the face, you cannot us bluetooth and wifi at the same time. If you want to watch netflix while listening with Bluetooth headphones, forget it. It will work at first but the wifi speed slows more and more until it just stops. Contacted customer support and they told me that the specs never said you could use both at the same time. As for the wifi signal problem, and gps, they just ignored my emails.
I worked for a major computer hardware company doing hardware teasting. These problems would have been found right away with the most basic testing. Asus had to know these issues existed but instead of fixing the problems, the shipped the devices and let the customer deal with their defective junk and their non-existent support. ASUS takes the quick buck then discontinues the device, no longer providing support or updates to its customers. PLEASE, SAVE YOUR MONEY! AVOID ASUS
