If you are a frequent traveler then today’s review item is something you may want to keep handy in your laptop bag for your next journey. The D-Link All-in-one Mobile Companion is a networking Swiss Army knife for road warriors, family vacationers or just home use. Like those late night infomercials this device can “do it all”. It is a portable router, wireless file streamer and media server, personal hot spot and wireless repeater plus it doubles as an iPhone or Android phone charger; pretty impressive for such a small and affordable device.
