Summary: Apple’s iPad 2

Today, Apple introduced the iPad 2, more of an evolutionary than a revolutionary improvement to the original iPad. This post summarizes what is new.
Hardware, compared to the “iPad 1”:

  • Shipping: March 11
  • Battery life: same 10 hours as before
  • Dual core processor: up to twice as fast, up to 9 times the graphics performance
  • Dimensions and weight: One third thinner, 15% lighter
  • 2 cameras: front VGA, rear 720p
  • 3-axis gyro sensor: complements accelerometer and compass to precisely detect your iPad’s orientation. Mainly interesting for games.
  • Screen resolution: 1024 x 768 (unchanged)
  • RAM (rumored): 512MB RAM
  • Pricing, Flash RAM: Same as old models

Add-ons:

  • HDMI output: capable of 1080p ($39 adapter). Can charge your iPad while in use.
  • Smart Cover: snaps on magnetically. The iPad goes to sleep if you close it and wakes up if you open it, presumably via the iPad’s ambient light sensor. Several colors, two materials: plastic for $39, leather for $69.
The Smart Cover, folded behind the back to prop up the iPad for video viewing or FaceTime. You can also rotate the iPad 180 degrees and put it flat in front of you for easy typing.

Software:

  • Configurable side switch: can either mute or lock rotation.
  • Video mirroring: shows what’s on the iPad’s screen and recognizes the current orientation (portrait versus landscape).
  • AirPlay: now streams video in addition to audio. Can be implemented by any app.
  • iTunes Home Sharing:  play content from your desktop iTunes on your iPad, via Wi-Fi.
  • Personal hotspot (an iPhone-only feature of iOS 4.2)
  • New included apps: Photo booth, FaceTime.
  • New Apple apps for purchase: iMovie, Garage Band.

Comments:

  • Smart Cover: is one of the most important features of the iPad 2. Apple has paid a lot of attention to detail.
    • Covering only the front is a good idea. Current cases also cover the iPad’s back, which adds significant bulk.
    • Especially Apple’s old case is difficult to put on and off, while the Smart Cover simply snaps on and off, magnetically.
    • Letting the cover (de)activate the iPad makes it feel like it is an integral part of the device, similar to the lid of a notebook.
    • Portrait mode: propping the iPad up in portrait mode is not well supported, but would be nice to have for FaceTime.
  • No Thunderbolt: It was probably too soon, but Thunderbolt will eventually enable killer features and, I’m guessing, replace the dock connector.
  • Competing with Android: The iPad 2 takes away the Android tablets’ key differentiator, dual-core processors. And it comes out sooner than most Honeycomb tablets.
  • Bringing back the physical rotation lock switch: Thank god! The software rotation lock is not very user-friendly, because you needed to many gestures to get to it. It is also awkward to access if you want to unlock and the iPad is already in a different orientation.
  • AirPlay: is a great for doing presentations wirelessly. You currently need a device like the $99 Apple TV to do so, but projectors might have built-in AirPlay support in the future.
  • RAM: If the iPad does indeed have 512MB (iPhone 4: 512MB, iPad 1: 256MB), then this is still not much. Most Android tablets have the more appropriate 1GB of RAM (but Android is less frugal with RAM than iOS).
More information:
  1. Apple’s iPad page
  2. The Next Six Months”: John Gruber thinks that Apple might introduce a high-end version of the iPad 2 towards the end of the year. It would complement the current line up and have a higher-resolution display, likely twice the current resolution (four times as many pixels).
  3. iPad 2 first hands-on! (update: even more video!)
  4. Apple's Digital AV Adapter also works with iPhone 4, fourth-gen iPod touch, and first-gen iPad

I'm afraid I don't understand why an iPad is showing up in the Java DZone ... java doesn't run on it. In this age of information overload, I look to specific topic boards like java.dzone.com to show me only relevant content. I don't see why this article is in this category.

True. While I’m its author, I didn’t put the article here, but I will try to get this fixed.

Well, on the site, I see it in the Mobile Zone, so it is understandable.

But indeed, I saw the article in the Javalobby RSS feed. Perhaps they though programmers are technophile...

I promise I only post the 1 or 2 major iOS related stories that happen each year.  I think this is one case where the general audience would be interested - even if it's only interest from a consumer standpoint.
