Today Apple introduced the new iPhone 5. It has a new design, however it looks a bit like tall iPhone 4S.

It is 18% thinner than the 4S, just 7.6mm. It's even 20% percent lighter at 112 grams. The in-cell retina display is 4-inch with 1136 x 640 resolution. Apple says new iPhone 5 has a better color saturation with full sRGB rendering. That new longer screen allows for an extra set of icons to be displayed on the home screen, and first party apps have already been tweaked to take advantage of additional pixels. The tweaked ratio puts the iPhone 5 display closer to 16:9, but it's not quite there.

iPhone 5 supports worldwide LTE as well as HSPA+ and DC-HSDPA. 802.11n Wi-Fi can connect at 2.4ghz and 5ghz. Performance is said to be 2 times faster with new A6 processor. iSight camera features 8-megapixel sensor, backside flash, hybrid IR filter, five-element lens, sapphire lens, f/2.4 aperture, next-generation ISP, spatial noise reduction, smart filter, better low-light performance, 40 percent faster on photo capture, and HD video recording (1080p) up to 30 frames per second with audio.
Front FaceTime HD camera has 1.2MP sensor, improved video stability and is capable of recording HD video (720p) up to 30 fps. Audio system was also improved. iPhone 5 has 3 mics and improved speakers.

AppleInsider claims that Apple is expected to adopt and start supporting the new faster 802.11ac Wi-Fi specification into products this year.

The new 802.11ac standard achieves much faster wireless networking speeds than the existing 802.11n specification (in use on the latest Mac, AirPort and iOS devices) by using 2 to 4 times the frequency bandwidth (from 80 to 160MHz), more efficient data transfers through sophisticated modulation, and more antennas (up to 8; existing standards support up to 4, while Apple's Macs currently use up to 3).

This "Gigabit WiFi" offers speeds 3 times as fast as existing 802.11n wireless networks can with speeds of over 1 Gigabit per second.

Few hours ago Steve Jobs presented two new MacBook Airs, which became the result of hooking up the iPad and a MacBook (according to his words). They have neither hard nor optical drive, as they keep all the data on the solid state drive. Here is how Steve Jobs explained such an innovation:

"MacBook Air is the first of a new generation of notebooks that leaves behind mechanical rotating storage in favor of solid state flash storage. We’ve taken what we have learned with the iPad—solid state storage, instant-on, amazing battery standby time, miniaturization and lightweight construction, to create the new MacBook Air. With its amazing responsiveness and mobility, it will change the way we think about notebooks."

When Gizmodo showed new iPhone's prototype most of us stopped expecting from Jobs anything shocking on WWDC 2010. But he amazed us, and not only with new display's resolution, FaceTime function and 802.11n support, but also with gyroscope. Many developers instantly realized - this is a new breakthrough.

While conventional accelerometer measures linear acceleration as a change of direction apart a change in velocity, a gyroscope measures angular acceleration, or in other words, a change in both direction and velocity at the same time. Thus the device can sense its rotation while ignoring hand jitters and linear movements, which is impossible for accelerometer.
