If you've been eyeing up Google's latest Nexus 7 tablet but needed a little something to tip you over the edge, then this might give you the incentive you need. Google and ASUS have teamed up to offer £50 credit to spend on Play Store content if you purchase a 16GB Nexus 7 between now and June 1st. There's also some good news if you bought your Nexus earlier in the month: ASUS says that any purchase made from a UK retailer after May 5th will qualify. If you have your Nexus 7 in hand, all you have to do is head to this site within 30 days and follow the instructions to redeem your credit.
