Eagerly waiting for some swivel screen action on the upcoming Nikon D5100? Well friend, you just got lucky, as said camera has just hit the shelves of Best Buy a few days early. The mid-range DSLR kit is now up for grabs either online or in stores for $900, but we expect Nikon to start shipping body-only options soon after -- Amazon and Adorama are already taking pre-orders for $800. Unfortunately, it looks like the accompanying ME-1 external mic won't be here until the original April 21st launch (or so we hope), but we're sure all Nikonians will be just fine without it over the next four days. Now go check out your local Best Buy to nab one of these swivelicious cameras.
