I've been waiting since May/June 2013, frustrating isn't it? Patience is a virtue I keep telling myself! I'm just about coping, but memory is becoming a bottleneck for me and I don't see any point in getting any more at this point when I could get a new machine soon. At this point I suppose it will be nice to get to 5 years with my '09 mini, which will be in March I think. Pretty good longevity for a desktop isn't it?
5 years is very solid. I just passed 5 years on my MacBook and celebrated by putting in a fresh SSD and doing a clean install of Mavericks. The machine still does enough for what we need but I will be buying a new Mini as soon as it's released.
