I'm a big fan of iFixIt's teardowns and ratings for tech gear. When I was running an IT department for a school, the ability to repair and upgrade a device easily was a significant factor in hardware choices. In particular, being able to add memory to extend a device's life and easily repair or replace a keyboard (students can destroy keyboards) were important. The European parliament has revealed plans to introduce ratings, similar to those given by iFixIt, as well as other safeguards for consumers.
