" I think it’s possible to use an iPad as one’s primary device for professional-level content creation. Actually, scratch that. I’m positive it’s possible – because I’ve been doing it for the past three months, and I’ve been having a really good time.

"This hasn’t been one of those experiments-for-the-sake-of-experimentation in which someone temporarily forsakes a PC for another device in order to write about the experience. No, I’ve been using the iPad for my daily activities–running Technologizer, writing for TIME, CNET, and AllBusiness.com, and more – because I find it to be the preferable tool in multiple respects. I’ve been using it about 80 percent of the time, and using my MacBook Air about 20 percent of the time. I have no desire to go back."

That's using ZaggFolio, which is a really good keyboard for the iPad. Otherwise it would just be "reading and light productivity". See the pic with the article.

"Last year we reported on the effect of Google’s playable Pac-Man Doodle, so as a follow up we ran the numbers to see if the Les Paul Doodle consumed a similar amount of users time.<br />
"We looked at ~18,500 random RescueTime users who spent time on Google search pages. In previous time periods, users spent a very consistent 4.5 minutes (+/- 3 seconds) actively using Google search. However, when Google released the Les Paul Doodle, the average user spent 26 seconds MORE on Google.com than in previous time periods. On average, users spent 36 more seconds time on last year’s Pac-Man Doodle, so you would think that the Les Paul Doodle had less impact. Wrong. According to Wolfram Alpha and Alexa, Google’s daily unique vistor count is up to 740m versus the 505m last year.<br />
"Google’s Les Paul Doodle consumed an additional 5,350,789 hours of time versus the 4,819,352 hours consumed by the Pac-Man Doodle."<br />

Google's daily unique visitor count is up by 46% in a year??
