Many of us like to, or are often forced through work commitments, to travel around on a frequent basis. As a hardcore geek, blogger, and general Internet obsessive, I take my MacBook Air pretty much everywhere I go, but as any seasoned journeyman would vouch, plugging in for a charge at any given location can be a trying task. With so many variants of the two-pin plug aiming to make life as difficult for somebody like myself, who has only ever used the three-pin here in the UK, it winds up being another annoying thing to tick off the list of pre-travelling to-dos.
