A couple of weeks ago, a co-worker asked me the one thing I absolutely could not travel without. My immediate response, a mobile WiFi hotspot. A while back, I told you guys about Skyroam, and how it was virtually a life saver as I, literally, wandered the streets of Madrid looking for an apartment. Well, they've released a newer version of their hotspot device, the Skyroam Solis, and it is bees knees! I'd already affirmed that it's the one thing I couldn't travel without, but that sentiment was re-validated on my recent trip to Amsterdam...
