The BBC has begun delivering its tiny Micro:bit programmable computers to students today, with every Year 7 in the UK due to receive theirs over the next few weeks. The spiritual successor to the BBC Micro, which introduced a whole generation to computing back in the early eighties, was originally due to reach classrooms last October, just in time for the start of the new school year. Power supply problems and then "fine-tuning" issues manifested in significant delays, but after overcoming these setbacks to get the first batch to teachers in early February, it's finally time for kids to get coding with Micro:bits of their own.
