I voted Mac mini, as I'm planning on buying one and am excited for it... not that I expect any major changes. But I'm curious to see if the Intel graphics are actually a big improvement.
I'm curious to see what the iPhone 5 turns out to be, as I'm eligible for an upgrade this year, but truth be told I'm 100% satisfied with my iPhone 4, so the new version is not as big a deal as I thought it might be...
That said, I was pretty happy with my 3G before the iPhone 4 leaked, too, and then the leak changed everything.
