Looks like some do, some don't, which is about what you will get with any review - but...
My two cents worth - I've been using the S530 keyboard and mouse a little over a year on my mini, and I am well pleased with it. I like the feel of both devices and they are excellent on battery usage. I am only on my third set now. I do wish they where both the same size, but you'll need a stock of AA and AAA's.
The only downside, is that I did have to download the updated drivers from the Logitech site when I purchased it. It also caused the bluescreen when I did an upgrade to Leopard, but an A&I fixed it. A victim of the Unsanity software. You may need to go to System Preferences once the drivers are installed to give it a nudge to start it working.
On a scale of 1 to 5, I'll give it a four - the one point lost for the bluescreen.
