When fired point blank, plastic BBs can hurt as much as rubber bullets, however most people engaging in military simulations with airsoft guns wear thick military garb. Additionally, precautions are taken to protect the neck, face, and eyes. Many people chose to wear a balaclava around their face and neck and lithium ion battery stocks ANSI approved eye protect is a must. The only place that plastic BBs can really cause damage is to your eyes.
This model has a 8.9-inch touch screen display. It is a LED back-lit display and supports a variety of multi-touch gestures (which was a lot of fun to use!). The screen can be rotated 180 degrees to face outwards. Some of the other features includes a VGA port, 2 USB ports, audio jacks and a memory card reader. Instead of using the usual lithium-ion battery, this model is powered by a lithium facts-polymer battery.
This can be a problem for where the battery is not used that often but is can be important when it is needed for emergencies such as power outages. As the battery does not store well over extended amounts of time, it is possible that when they are needed they will not be usable. But for things that are used and recharged on a regular basis such as for portable electrical equipment, they are very good. But there is not always a slowing amount of capacity when they are getting old and it is possible for them to just not work without any reason being obvious.
No. There will almost certainly be many people who have to go without a lithium bettery stock PS for Christmas despite being willing to pay the very high price Sony is asking. But, that's nothing new. Other consoles (including the Xbox 360) have been launched without an adequate number of units immediately available for sale.
All power tool batteries degrade over time and lithium ion batteries degrade more rapidly over periods of un-use. Accordingly, use them often and when you're not in the trenches of a project, try to use them at least once each month.
With any battery, every time you charge it, it loses a bit of its performance and power. Over time, that battery will die, and after you give it a proper funeral, you'll have to change it. The same is true with your iPOD. Eventually, you will have to replace the iPOD battery. You can either change the iPOD battery itself or purchase a new iPOD Nano . But, because your iPOD battery is a lithium-ion beast, you won't need to worry about that for a while!
