UK supermarket Tesco appears to be on to a winner with its £119 Hudl tablet. After notching 35,000 sales in its first few days on sale, the chain says healthy Christmas demand helped it offload more than 400,000 units in the last three months of 2013. While the figure isn't likely to have heavily impacted sales of Google or Amazon tablets, it's a very healthy start for the Hudl, which aims to keep customers locked to the brand by offering grocery orders and movie downloads via its custom apps. With Tesco set to refresh its Hudl lineup later in 2014, its year-end sales undoubtedly prove customers like being able to pick up a low-cost tablet along with their bread and milk.
