Everyone who's ever owned a PC knows what mice look like, but that doesn't mean there aren't mice that look like completely different objects. Genius actually has one that looks like a fountain pen.
The Pen Mouse actually isn't a new invention, although the latest iteration of it has only been on the market for a short while.
Colored carbon grey or silver, the Wireless Comfortable Pen Mouse sells for $49.99, which is the same as 37 Euro according to exchange rates.
Of course, given how rarely exchange rates are reflected in reality, the probability is much higher for the EU price to actually be of 49.99 Euro.
That said, the name hits the first nail on the head, namely that the shape of this mouse is not the only unusual thing about it.
Granted, wireless support is not exactly rare on mice nowadays, especially the type that use the 2.4 GHz wireless band. Still, that the mouse is both atypical in shape and wireless deserves mentioning.
Speaking of the wireless support, the link to the PC is done through a pico receiver that goes into a USB port and stays there.
Moving on, Genius' latest creation can perform hyperspeed scrolling, 4D scrolling (uses a touch scroll) and can work on any surface.
That last capability is actually the main asset that the Wireless Comfortable Pen Mouse has over the previous-generation Pen Mouse.
And by any surface Genius really means any surface, like clothes, desktops, human skin (in one's palm if needed), etc.
Other features include adjustable sensitivity (three steps of 400, 800 and 1,200 dpi) and ambidextrous usability.
Genius' press release can be found here, but the product page, where all the information is neatly listed, is here. As the photo shows, the mouse resembles a marker more than it does a pen, but that's just an issue of semantics.
