If you've ever been involved in building out a large scale network, you've undoubtedly heard about single points of failure. The BlackBerry network itself is a single point of failure as we saw last week: if it goes down, every single person that relies on BlackBerry email is hosed (pun intended: it is a Canadian device!). But for you personally, the biggest single point of failure is probably your battery: if you run out of juice and you don't have your travel charger, you are, well... hosed.
Which is where the latest BlackBerry accessory I found comes into play: an
Emergency Cell Phone Charger that runs off of a couple (four to be exact) double AA batteries. This gadget can be used anywhere: it generates an extra 20-30 minutes of talk time, when your battery is drained out and fits in your pocket or purse. Pick one up now before your battery runs out!
