Sony comes up with these awesome gaming device and here is one of its best products. We listen to songs, watch movies, play games hence it can be called as a multi usable device.
The internal memory is 4 GB which I feel should be increased but I had no problem as I used a memory card to expand it.
The buttons and the response system is really good and most of the games run without any lag.
The battery backup is pretty good if you charge is reasonably.
You can connect it to with wifi, Bluetooth and USB. This adds it to ton of other exiting features!
