Best secondary gadget for me in 2010 would be the iSpot. The 4G service was ok, but what was really nice was the hackability of the device. Out of the box, I had to hack it just to get my iPad to work, due to their MAC filters not being quite right with the initial release. While nowhere near as convenient as having WAN service built into a device, having a $25 data plan along with no contract was nice. It's not seeing any use for me in 2011 though, as the 4G WiMax network Clear built for LA isn't reaching me here in south Orange County.
