I need to do a write-up on the stats from my Hacker Newsletter project, great idea. According to the MailChimp stats I have about 45% of subscribers using mobile devices and of them about 99% using iPhones... but I just don't see that being the case. Need to look into that more.

What did you see in terms of locations? Last time I checked it was around 50% of the subscribers were from the states and the UK second with about 8%.
