Once you take the time to get to know the R2 Mark II Gaming Mouse it’s a great piece of hardware. It’s smooth, fast, precise and versatile, but it does take some time to actually read the manual, and maybe even create a custom hardware profile. Otherwise, the small size and circular design can throw you off, as it has the feel of the old and quite unsuccessful Apple “hockey puck” mouse. There was an announcement, or maybe just a rumour, that a Mac version of the programming and application-awareness software would be available soon, but it’s been a while and I haven’t been seeing more on that, so don’t hold your breath. In the mean time, I’ve been meaning to update my Parallels and Windows XP and try programming it there. More here, if I get around to it.
