Much lighter and less expensive than the other inverters at Fry's and a higher wattage to boot. Makes me wonder what I missed that people sell heavier, more expensive, with less wattage inverters. . .

Glad you like it, the APC UniversalPlug. It is the smallest, lightest and least expensive world adapter I've seen. I don't know why that virtually nobody knows about it. I wouldn't have either except for noticing it in an inconspicuous area at Fry's.
I bought the Kensington 120W Universal power adapter myself and use it as a second adapter, so the laptop has adapters in place in the office and living room without constantly moving one around. With this adapter and the tips, this is the only power adapter I need to take for all of my devices. Inverters apparently work well but don't lessen (actually increases) the number of device power adapters one needs to pack.
