Ever since I decided to ditch the desktop for the laptop, I was looking for the wireless mouse I will use with my future mobile platform. Since my choice of laptops (ultra-portable) has very limited amount of USB ports (Sony SZ has two) I did not want to permanently occupy one of them with USB receiver for the mouse.
This ruled out majority of mouses out there and left me searching Bluetooth options.
In reality, there were two: Microsoft and Logitech. All the others was not really good ones and all belonged to entry level class. However, both MS Intellimouse and Logitech MX900 are designed for the right-hand users and I happen to use the mouse with my left hand. I am right-handed person but I strongly believe that mouse should be used with left hand as that is more comfortable than the usual way. I eventually bought MX900.
For its own, it is an excellent mouse, which works on practically any surface, even mat-black as my working table. However, it soon became obvious that it was very battery consuming and it having a charging cradle naturally leads me to think it’s a BT mouse aimed to be used in desktop situations.
