An anonymous reader points out a report at the Guardian of a potential problem for early adopters of the Microsoft Surface tablet. The Touch Cover is one of the available protective covers for the device; it acts as a keyboard, and has both a gyroscope and an accelerometer on board. Unfortunately, some users have found that the edges of the Touch Cover have split open after only a few days of use. "The defect is identical in each case: the cover ... begins to split at its seam where the device attaches magnetically to the main computer. [One developer] was told to return his Touch Cover to Microsoft for a replacement, and Microsoft has been swapping faulty covers for users where it has retail stores. It's unclear whether the problems that people have encountered are due to a faulty batch or are a subtle problem that will become more apparent as more people use it for longer — but the fact that users in the US and the UK have reported the problem suggests that it is not isolated to a single manufacturing batch."
