Another concern has cropped up with Facebook, highlighted by Nick Bilton of the New York Times. For people looking to spread the word on Facebook, traffic in the form of “likes” and resharing would seem no longer to be organic, but must instead be greased with a little green. That’s mostly a problem for those doing some sort of business promotion on Facebook, but should give anyone considering Facebook as part of a marketing strategy significant pause.

Beware Country-Specific iTunes Stores
If you buy an iPhone, iPod touch, or iPad, and you happen to be a user of the iTunes Store in more than one country, take note which country's store you're viewing in iTunes when you plug in the device for the first time. This will be the country the device will register with, and you will be forever barred from purchasing or even updating free apps from anywhere else. The only way out is to delete everything on the device and do a full restore.
