Twelve South PlugBug World
Twelve South announced the PlugBug World early this year, and I'm baffled it isn't sold in Singapore, not even on the Apple Online Store. So when Li Xiang visited Hong Kong, she bought it for me for HK$348, about S$60.

Twelve South PlugBug Charger
I bought the Twelve South PlugBug Charger at the Apple Store in Fashion Show Mall, Las Vegas, for US$34.95, or US$37.78 after tax. It acts as a US travel adapter for your MacBook's MagSafe adapter, plus an extra USB port.
