My battery was about 50%...
after an early 7:00am start with the use of my Google Maps for about 1 1/2 hours, I made 2 forty-minute phone calls, made and received about 20 calls, sent at least 50 text messages with responses via email/text/phone call, constantly adding WebApps, searching AppleWebApps, searching for WiFi signals "all-day" while at Macworld, listen to my music and demonstrate "Star Wars Episode IV - "A New Hope" to several interested vendors and iPhone owners, checking emails on the half-hour, and looking for a particular restaurant in Japantown in San Francisco, and checking my "Location" with the new "Replace Pin" TOY on my iPhone... and more surfing on the web until about 10:00pm tonight. 😎
