Intel's new Compute Stick isn't that hard to grasp: It's a computer... on a stick! Using one of its Atom processors, Intel managed to cram everything a fully functional PC needs in something the size of a few packs of gum for just $150. All you need to get going is to plug it into a display with an HDMI port, connect it to power and attach your accessories. It heralds a new era of computing, one where you can turn any display into a pseudo-desktop in a few minutes. It could change the way IT workers manage computer labs, kiosks and digital signage forever. And it's something you should avoid buying at all costs. While the Compute Stick gives us a glimpse at a tantalizing future, it's basically a beta product. It's only meant for the brave and geeky -- not most consumers.
