If youve been eyeing up Googles 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. Theres 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.
