There is no need to explain the importance of a mouse as a controlling device for any PC user. It's hard to imagine that there may be an alternative to this well-known device that we've got accustomed to. Yet, it's not the fact that the traditional shape of the mouse is the most convenient and efficient one. Thus, some designers think that there is a possibility to change the way mouse looks. The proposed gadget being a wireless mouse looks like a standard pen. Actually this unique device functions as a simple pen as well enabling you to put down everything you want, but when you detach the receiver and insert it into your USB port, the pen turns into a wireless mouse. So functionality and portability of the concept represents its key advantages in comparison with a usual mouse.
It has three buttons positioned on its side in the row. So the user can still have the three buttons to use. However, it does not have a scrolling wheel, which reduces its usability.
I have no doubts that this gadget is great for casual browsing; however, if you deal with graphics design or something like this, you will probably encounter some problems, at least at the first dash. No information is available about refillable cartridges, but I hope that the pen comes with them, because otherwise it would be a waste of money to purchase a new unit each time you need one. Nevertheless it is quite a decent idea that most likely will have its proponents.
