The Best Buy in St. Cloud, MN has several laptops and desktops from HP on display running Windows 8. Based on the reports, the computers are running demo versions of Windows 8 to give you a feel for things. While you can check these new computers out in the store, you can't take them with you just yet. While the computers are in stock, Best Buy is only taking pre-orders for the HP Windows 8 computers.
If you're interested in checking out the new computers and Windows 8, it might be worth a ride to your local Best Buy to see if they have the display units out. If you don't have a Best Buy nearby, fear not. You can go to Best Buy's website to see all the Windows 8 computers they have in inventory and pre-order online.
