It's not a PR campaign, but even though I don't have addictive personality I have this thing for a week already and just keep asking myself, how did I ever live without it before? How did I find places without build-in GPS? I can't stop being amazed with all these new applications I get to download and play with every day, not to mention access to the emails accounts, work calendars, restaraunts to eat, facebook, etc etc...
Are you also part of i-phone therapy group as me?:)
