As I have discussed in recent posts, most of my mobile computing tasks have been transferred to the outstanding Droid phone. It now is my principal calendar, email, instant messaging, SMS messaging, music, twitter, ereading, and online mobile search device. I always get a signal with Verizon Wireless, and have yet to have a dropped call. The battery is long lasting, lasting almost twice as long as my iPod Touch battery. And, I have a spare battery that slips in my pocket that doubles that time. I haven't had to use it yet. I still use the iPod Touch, as the Slingmobile app allows me to connect to my home cable box, and the games are better because of the larger internal iPod memory. However, I seldom play games, and rarely need the Sling app. When I do use it, it is really annoying to run out of battery after less than an hour of streaming video. So, you need to supplement the iPhone 3GS and iPod Touch internal battery with an external one. This one is nice, but adds weight and heft to the iPod Touch. Still, it is nice to get enough juice out of the battery to watch all of the pregame shows before Sunday football, at the game.
