Apple Store SoHo (Score 1)

Like someone mentioned previously, the Apple Store in SoHo will happily sell you a brand new PowerBook or iBook G4 and let you walk out with it that day (assuming, of course, they're in stock which they should be).

Not only that but I know for a fact that Apple's portable power supplies for their laptops are auto-switching for both US and UK (and other) power standards -- the only thing that needs to be adapted is the physical plug itself and you can get those adapters either in the store or at any major electronics store or travel agent.

Also, Apple's laptops rule.
