Summary: This product is GARBAGE. The built-in wireless adapter does not work. With no CD drive or ethernet port on these streamlined convertibles, the user is wholly reliable on wireless. I had to replace it. Problem is, I had the exact same problem with the second, replacement computer. The built-in wireless card adapter did not work a second time! And don't just take my word for it. Reports of this same issue are all over the Internet!
Summary: When the tablet is on battery (DC), the refresh rate changes to lower than 60Hz automatically which may not be noticeable under the naked eye but is discernible under a camera (screen flicker). This can potentially strain your eyes without you realizing it. There are many videos of the Sony Duo on Youtube and you can verify for yourself. When AC power is plugged in, the refresh rate changes back to 60 Hz automatically.
Summary: I purchased this so I could annotate lecture notes during class and later print them with my annotations included. I bought this from a Sony store near me and first thing I noticed was how rickety and unstable it was. The screen wobbled a lot when it was deployed but the writing on the screen looked great. I opened my .pdf documents and annotated them, occasionally saving my work.
Summary: Ordered one online from bb, delivered no problem but short the software I ordered. Used it for a week, nice but took it back due to hassle trying to get software ordered and paid. Return was easy. Purchased an Asus, less than half the $ touch screen windows 8 etc but no screen rotate....but Sony has a very small hard drive.
