When it comes to travel they say there are those who overpack and those who underpack, but I often veer between the two, overcompensating for errors I made on the last trip. Do I need both cameras? Can I survive with just the trackpad? Or do I have to pack a mouse and freaking mousepad because the typically glass-topped hotel desk will be too shiny for my mouse to pick up?
One item I've learned I absolutely cannot live without is this World Travel Adapter I picked up in Sweden, though it's actually by Swiss manufacturer Skross.

Prior to owning one of these I had to go into my "travel toolbox" and dig through a Lego-like series of adapters I thought I'd need, which is a pain on backpacking trips where you're not sure which countries you'll be in. The Skross here covers about 150 countries.
The design is at least several years old, but I now see the company is up to the World Travel Adapter 3, which comes in Swiss identity colors and has just scooped up a Red Dot Design Award.

It'll even handle a hair dryer without frying up--I learned the hard way that your standard Radio Shack travel adapter will not. I just wish it came with the USB adapter featured on the WTA 2, below.

Well it looks very similar to currently available travel adapters such as one below, the Swiss one seems to have a retractable prong for earth, though.

It looks good, but it is not recommendable for German users: You cannot insert SCHUKO plugs in it!
Of course they sell it in Germany without stating that. I am quite pissed...
