In April 2012, Apple started shipping a slight variant on the iPad 2 that remains for sale even as the third-generation iPad has become the mainstay of the line. This new version of the iPad 2 — labeled internally as “iPad 2,4” — uses a 32 nanometer version of Apple’s A5 chip that replaces the 45nm version in the previous iPad 2 model. The processing performance is the same, but AnandTech is reporting that the 32nm model has notably better battery life (and a lower manufacturing cost). Alas, there is no way to know if any given iPad 2 uses the new chip without running an app that reports on the internals. follow link
Disinfect Your Keyboard
Keyboards, particularly those shared by multiple people, harbor huge quantities of bacteria. If you want to reduce the chances of picking up your co-worker's cold, you can disinfect your keyboard with disinfecting wipes. To avoid damage to the keyboard, be sure to:
- Unplug the keyboard before disinfecting it.
- Squeeze out any excess liquids from the cloth to avoid liquid dripping into the keyboard.
- Don't let any liquid from the wipe sit for long periods of time on the keyboard.
- Don't scrub the keyboard, just lightly wipe down. Rubbing too hard leaves behind more lint.
- Avoid cleansing cloths that contain bleach.
