A day in the life of an iPad

Today was the first day I traveled only with my iPad.   Here is how the day went:
6:45-7 AM - downloaded four documents for use in a meeting I was having this afternoon in San Diego.
7:00-7:20 AM - While eating breakfast I scanned the Wall Street Journal. (Their implementation of the platform is really well done!!)
7:30 AM - before leaving I did a map search of the location I was traveling to this afternoon.
9:00 AM - As I left the gym - I did a quick search of Email and looked at my portfolio
9:45-10:25 AM - while waiting for my flight I checked email and my RSS feeds
11-Noon - Read while on the flight a book on the Fast Ball (called High Heat)
12:30-12:45 landed and responded to an urgent email about an issue that I am working on.
1:30-2:30 - Arrived early for my meeting and used the time to surf the net.  Read and respond to email, including using the Bluetooth keyboard to draft a lengthy response to one email.  Also did some searching for a location we are thinking of buying with a business associate.
3-5:15 PM - in a meeting, checked and responded to email.  Searched the net on a couple of issues.  Reviewed a couple of email sites.
5:25-6 PM - after doing a couple of phone calls I read some more on the book.
7:20 PM-8 PM - after arriving at the airport, worked on WIFI there on a number of projects including polishing a presentation I am doing on Friday.
8:20-9:20 - Read a book on the flight back to Sacramento - this one on the economy.  The Kindle Ap needs to be upgraded.  I think the highlight feature does not work as well as on the iBook Ap - but I still have not found how to out put either to a text file.
9:35-9:45 - Quick check of Email before I left the airport (Free WIFI at Sacramento Airport).  
10:30 Arrived home - current battery capacity 48%.   From my rough estimate that amounted to a bit more than 8 hours of use during the day.

Two conclusions - First, I have adjusted the screen down a bit, which uses a bit less power - it is still plenty bright.   Second, I suspect had I pounded the Bluetooth keyboard a bit more I suspect the battery life would have gone down.  But my guess is that I was on the net for a total of a couple of hours today at various WIFI spots.

One evaluation - The battery life that was promised seems to hold up.  I have two phones (a 3G and a 3GS) both were on the verge of being out of power at the end of the day.  I spent perhaps 80 minutes on the phone today in calls and some more time playing games.   This device seems to live up to its promises and more.
