Sometimes names can be deceiving. In the case of the Pogoplug Pro, "Pro" really means a very useful added feature for no extra money at all. Cloud Engines' plug-and-play device turns any form of USB storage into a networked drive; it previously required hardwiring via Ethernet, but the Pro version adds 802.11 b/g/n Wi-Fi for even easier use in a home or office. As before, the Pogoplug Pro retains 4 USB ports for hard drives/flash drives as well as an Ethernet port for those who prefer speed.
Available exclusively at Best Buy, the $99 device is the same price as the last Pogoplug, making your decision a no-brainer. It also loses the frankly hideous pink look that made it resemble an iMac that time-traveled from 1999.
