2010 apple iPad pictures

The iPad is a tablet computer designed and marketed by Apple, meant for internet browsing, media consumption, gaming, and light content creation. Unlike many older tablets, it uses fingertips for input instead of a stylus. Released in April 2010, it introduced a class of devices between smartphones and laptops.

Like the older iPod Touch and iPhone devices, the larger iPad runs the iPhone OS and uses a multi-touch LCD for most user interactions. It runs iPad-specific applications as well as those written for the iPhone and iPod touch, including e-book readers.

The iPad uses WiFi or Wireless WAN to browse the Internet, load and stream media, and install software.

History and availability

Apple's first tablet computer was the Newton MessagePad 100[22] introduced in 1993, which led to the creation of the ARM6 processor core with Acorn Computers. Apple also developed a prototype PowerBook Duo-based tablet, the PenLite, but did not sell it to avoid hurting MessagePad sales. Apple released several more Newton-based PDAs, and discontinued the last, the MessagePad 2100, in 1998.

Apple re-entered the mobile-computing market in 2007 with the iPhone. Smaller than the iPad but featuring a camera and mobile phone, it pioneered the multitouch interface of iPhone OS. By late 2009, the iPad's release had been rumored for several months. Mostly referred to as "Apple's tablet", iTablet and iSlate were among speculated names. The iPad was announced on January 27, 2010 by Steve Jobs at an Apple press conference at the Yerba Buena Center for the Arts in San Francisco.

Three days later, at the 52nd Grammy Awards, Stephen Colbert used an iPad in announcing the nominees.

Apple began taking pre-orders for the iPad from U.S. customers on March 12, 2010. The Wi-Fi version of the iPad went on sale in the United States on April 3, 2010, at 9:00 am local time, with hundreds of customers lined up outside stores nationwide. The Wi-Fi + 3G version was be released on April 30. 3G service in the United States is provided by AT&T and sold with two prepaid contract-free data plan options: one for unlimited data and the other for 250 MB per month at half the price. The plans are activated on the iPad itself and can be canceled at any time.

The iPad will also be available in Australia, Canada, France, Germany, Italy, Japan, Spain, Switzerland and the UK at the end of May 2010.[6] Apple stated they will announce international pricing and begin taking online pre-orders for iPad on May 10.

Israel recently authorized importation of the iPad, after a prohibition related to possible Wi-Fi interference with other devices.

Hardware

Back of the iPad Wi-Fi

Screen and input

The touchscreen is a 25 cm (9.7 in) liquid crystal display (1024 × 768 pixels, 132 ppi, XGA) with fingerprint–resistant and scratch-resistant glass. Like the iPhone, the iPad is designed to be controlled by bare fingers, not gloves and styli that prevent electrical conductivity (although there are gloves and styli designed for this use).

The display responds to two other sensors: an ambient light sensor to adjust screen brightness and a 3-axis accelerometer to sense iPad orientation and switch between portrait and landscape modes. Unlike the iPhone and iPod touch, which work in three orientations, the iPad supports screen rotation in all four orientations, meaning that the device has no intrinsic "up" or "down"; only the position of the home button changes. Most iPad applications support both portrait and landscape mode.

The iPad has a switch to lock out this screen rotation function (reportedly to prevent unintended rotation when the user is lying down). There are a total of four physical switches, including a home button below the display that returns the user to the main menu, and three plastic physical switches on the sides: wake/sleep and volume up/down, along with the screen rotation lock.

Connectivity

The iPad can use Wi-Fi network trilateration to provide location information to applications such as Google Maps. The 3G model contains A-GPS while both models have a digital compass.

The back of the Wi-Fi model iPad is made of contoured aluminum with black plastic buttons. The Wi-Fi + 3G model also has a black plastic accent on top of the device which helps with 3g radio sensitivity.

The iPad does not have any ports for wired connectivity.

Audio and output

Dual speakers housed inside the iPad provide mono sound via two small sealed channels in the interior speaker assembly that direct the sound outwards toward the three audio ports carved into the bottom-right of the unit. The microphone is within the device. A volume switch is on the right side of the unit, and a 3.5 mm TRS connector audio-out jack provides stereo sound for headphones on the top-left corner of the device. The iPad supports normal headphones and models with microphones, volume controls, or both. Microphones can be used for voice recording.

The built-in Bluetooth 2.1 + EDR interface supports the HSP, A2DP, and HID profiles, which allow wireless headphones and keyboards to be used with the iPad. However, the iPhone OS does not currently support the OBEX file transfer protocol.

iPad video output over VGA is set to 1024 x 768 using a 720p scan rate.

Power and battery

The iPad uses an internal rechargeable lithium-ion polymer battery. The iPad is designed to be charged with a high current (2 amperes) using the included USB 10 W power adapter. While it can be charged by a standard USB port from a computer, these typically provide lower current (500 milliamperes or 1 ampere). As a result, if the iPad is turned on while being charged with a normal USB computer port, it will charge much more slowly, if at all.

Apple claims that the iPad's battery can provide up to 10 hours of video, 140 hours of audio playback, or one month on standby. The battery loses capacity over time and is not designed to be user-replaceable. As in the battery-replacement program for iPod and the original iPhone, Apple will replace an iPad that does not hold an electrical charge with a refurbished iPad for a fee of US$99.

Storage and SIM

The iPad was released with three options for internal storage size: a 16, 32, or 64 GB flash drive. All data are stored on the flash drive and there is no option to expand storage. Apple sells a camera connection kit with an SD card reader, but it can only be used to transfer photos and videos.

The Wi-Fi + 3G model has a micro-SIM slot (not mini-SIM) located on the side of the device. The 3G model may be used with an AT&T data plan that does not require a contract. Apple has heavily advertised the uses of the no-contract plan on their website. Unlike the iPhone, which is usually sold locked to specific carriers, the 3G iPad is sold unlocked and can be used with any compatible GSM carrier.

Optional accessories

iPad in the iPad Keyboard Dock

Apple offers several iPad accessories, including:

  • iPad Keyboard Dock with hardware keyboard, 30-pin connector, and audio jack
  • iPad Case which can be used to stand the iPad in various positions
  • iPad Dock with 30-pin connector and audio jack
  • iPad Dock Connector to VGA Adapter for external monitor or projector
  • iPad Camera Connection Kit including a USB Type A connector adapter and an SD card reader, for transferring photos and videos
  • iPad 10W USB Power Adapter with 2 A output (10 W)

Sony Ericsson MW600 Review

If you're someone who regularly finds themselves driving, or cycling, or skiing, or cooking, or cleaning, or doing anything - for that matter - which requires your hands and at least a portion of your concentration, then you'll know the value of a Bluetooth headset. But in the more energetic of the aforementioned pursuits, you'll find that a regular ol' one-eared headset won't do. They fall out. When you're halfway down a Colorado piste, or leaning over your stew, the last thing you want that little bit of expensive plastic to do is fall out. Enter Sony Ericsson's MW600 - a teeny-tiny device with a big clip that lets you turn any pair of headphones into a Bluetooth headset. But is it worth shelling out your hard-earned cash for? Do you really need the MW600 in your life? Look down at your little finger on your left hand. The MW600 is about the same size as that. It has a clip on the back that reaches two-thirds of the w...

Roqbot Is A Jukebox On Your iPhone

Something unusual happened last Friday night at Bar Basic here in San Francisco. When I walked in, the entire room was fixated on on a screen above the bar, which displayed what looked like a musical game but wasn’t karaoke. The game? Roqbot, a unique iPhone app that allows you to yes, pick the music playing at a bar. Like a combination Pandora and traditional jukebox, Roqbot allows you to control the tunes without getting up from where you’re sitting. The inspiration for Roqbot came when one of the co-founders got frustrated using the jukebox at a bowling alley — Every time he had to walk across the bowling alley he would miss his turn. Roqbot, which shares the space with jukebox networks TouchTunes and eCast, is the first startup that I’ve seen experimenting with bringing social music to real life businesses like bars and cafes. Up until now plenty of people have deployed this concept for private settings, but no one has touched public because of the many challenges involved. Co-foun...
