Whine, whine, whine
From all the silly complains this was the silliest: "All the reviewers complained that it's [the charger] yet something else to pack in your briefcase when hitting the road."
Unless you are going to hit the road for at least two days I see no point why you should carry the charger if you plan to get back home in the same day. The same you do with any other Apple charger, don't you? At least, I am not carrying my chargers around if I know I'll be back home within the same day. All the batteries last just fine and I use the devices continuously.
So, how come carrying a tiny charger that weights close to nothing can be such a big problem?
Thinking about how the Apple Watch could be useful for me I remembered that when I am in cities like Barcelona, where I don't want to take my iPhone or iPad out from my bag for anything, the Apple Watch Sport at $349 could be a good thing to have to use maps, get notifications, send messages, etc. without exposing devices too much.
