We have been following pretty much every new cordless laser set releases from Logitech since 2005. As Logitech releases a new set every year, we are generally very impressed with pretty much all of them -- what makes it truly interesting is that, despite the fact that they are 'just' keyboards and mice, Logitech still manages to innovate in every successive release that makes their products convincing enough for a lot of people to upgrade from their existing set, yet retaining the originality and usability factor of the keyboard and mouse itself. What we are trying to say is making changes and improvements are one thing, but some companies ruin their products in the progress of modification. Logitech is certainly not within this category. As a new year arrives, so does Logitech with their latest Logitech MX5500 Revolution cordless laser set. Combined with the legendary Logitech MX Revolution cordless laser mouse, as well as a brand new Bluetooth keyboard, how does this keyboard and mouse set stack up against their previous releases? Let's check it out.
