Yes the do stock them in the Apple stores but you are unlikely to see them either on display or on the shelf, they tend to keep them in the back. Be prepared for plenty of dissuasive sales talk though as they will try to sell the negatives of buying a Mini and upsell you to the iMac - least this has been my experience at three different Apple stores.
It's funny that all the Best Buys I've visited (which is only about 10, not a big sample) have the current generation mini on display. Typically, though, it's not on display in the little Apple station area, but it's never that far away. They've always been on the stock metal shelving.
thats disappointing. Surely they can see there are a reasonable number of people wanting a HTPC and for that an imac is pointless - it'll block the view of my TV![]()
And this is how Best Buy usually displays the mini, as an HTPC hooked up to a non-apple monitor and to a HDTV instead.
