Someday you will own an iPad-like device →[More:]For the record: I am not a fanboi. I switched from Mac to Windows in the XP years and I've never regretted it for a moment.
That said, the iPad I am typing this on is - not to mince words - The Future. In 5 years, it - and competing devices trying to catch up with it - will be as common as laptops are today.
Its "killer app" is that it makes the Internet - and enough PC functionality to handle 80-90% of the Stuff People Do - literally ubiquitous. As in: Within arm's reach every minute all day long. In conjunction with SimpleNote, it has completely outsourced my short term memory.
