One of the things that people usually have problems with is switching from using Windows. This is not something that can happen immediately but as long as you are determined, you will understand how to use this better. The first thing that you have to remember is that the scroll pad will move in reverse. You also cannot expect that the one that you have right now will have a touch screen version.
It will probably have a new one in the future, but another thing to take note is that there are no DVD players too, unlike in Windows wherein you can watch some of your DVDs. Of course, you can still watch the movies you have saved on your device.
