A PC Magazine column takes a quick look at some technologies that are ready to change the world. Ranging from practical improvements on existing concepts (a 100 GB removable disc) to brand new (a DNA detector), these devices are all at least at prototype status. There’s also a nod to the standbys: a robot and VR glove are both included. The article is interesting mainly from the standpoint that it shows items that really are getting close to production.
