Big points to Steve Cencula of the design group FORM for his tongue-in-cheek photo showing the fastest and easiest way to print from an iPad.

Apple has released a statement saying that the unexpectedly strong demand for the iPad in the United States (over 500,000 units sold in the first week) and the large number of preorders for the iPad 3G will result in product shortages for a few more weeks. In addition, Apple is delaying the international launch of the iPad one month, to late May; pre-orders will be accepted starting 10 May 2010. It's a good news/bad news situation: the iPad is wildly popular, but so much so that it will be hard to get in the near term.

A Google developer, formerly on the Android team, provides a detailed, fair, and clear explanation of how iPhone OS 4 multitasking will work. Robert Love explains the difference between true background application multitasking and Apple's limited set of APIs that let certain processes continue to operate in the background. He also differentiates serialization (quitting an app while preserving its state precisely) and true background operations.

In what was perhaps the largest podcast we've ever participated in, nearly the entire TidBITS staff joined MacJury host Chuck Joiner to talk about the iPad. Topics ranged widely, including how it will be shared, the need for a guest mode, how we'll interact with it as an object, and where it will fit into our digital lives. But the real reason to listen is to hear Tonya compare using the iPad to "eating pudding with your fingers," an image that left many of us briefly speechless.

It's been an iPad- and iPhone-intensive week, and Adam took some time out in the middle to talk with Tech Night Owl host Gene Steinberg about the first few days of iPad hands-on, along with a run-down of the most interesting bits of Apple's iPhone OS 4 announcement.

A quiet change to Apple's iPhone Developer Program License Agreement takes the huge step of banning a number of cross-platform compilers such as Adobe's forthcoming Flash-to-iPhone compiler.

It was an iPhone OS blowout, with Apple announcing more features than it could even begin to cover for the upcoming 4.0 release of the operating system for iPhone, iPod touch, and iPad. Key among the features: specific multitasking capabilities, folders for app organization, and iBooks for iPhone and iPod touch. In-app iAd advertisements were also previewed, enterprise features explained, and gaming options given a boost. iPhone OS 4 is coming this summer for the iPhone and iPod touch and in the fall for the iPad, but not all older models can be upgraded.

At Apple's iPhone OS 4 sneak preview, Steve Jobs led off by sharing sales and download statistics related to last week's iPad release: iPad units sold so far, the number of app and book downloads, and - most impressively - overall iPhone and iPod touch sales volume.

Few writers put the kind of thought into user interface that John Gruber of Daring Fireball does, and that shows in his lengthy review of the iPad. It's very much worth reading for his detailed impressions in support of why the iPad is Apple's reconception of personal computing.

Hoping to capture her initial reactions, Todd Lapin had his camera ready when he first showed his iPad to his 2.5-year-old daughter. Aside from being cute, the footage is interesting for what it shows us about which aspects of the iPad interface are intuitive and which are less so. The clip also hammers home just how standard and ubiquitous this technology will become for the next generation.

With the release of the iPad, many have been asking how they can read the Take Control ebooks on Apple's new device, or on the iPhone or iPod touch. We explain the best approaches (and even give a nod to the Kindle).

Adam's favorite weather app for the iPhone, WeatherBug Elite, has been expanded for the iPad, and for a limited time, it's available for free. We haven't spent much time with it yet, but it appears to use the iPad's larger screen to good effect, devoting most of the display to the map, and providing four zoomable panels for conditions, cameras, forecast and hourly forecast. The main missing feature appears to be pin dropping and display, but WeatherBug's developers tell me they just couldn't get it in for the iPad launch, and plan to add it to an update, due in the next month or so.

As we spend more time with the iPad, we're discovering hidden functions and shortcuts to improve how we use it on a regular basis. Read on for a whole host of tips.

Apple's own user forums and other discussion sites are filling up with posts about problems getting a strong and consistent Wi-Fi signal on the iPad.
