From your latest gadgets to your expensive big TV and even your car, here's a complete guide about how to protect all your precious material things from thieves:

AT&T killed all-you-can-eat wireless data. Which sadly was inevitable. But if I'm paying for bytes like I do for minutes, why don't I get rollover data, too?
The premise of AT&T's new wireless data plans is simple. They've gone to the same pricing model for data that they've always had for voice. Just like paying $40 for 450 minutes of talk time or $60 for 900 minutes, you pay $15 for 200 megabytes, or $25 for 2 gigabytes of data. You're buying a set amount of data for a fixed price, so you pay per byte, just like you pay per minute. Same deal. It breaks down like this:

AT&T is the only major carrier in the US to offer rollover minutes as a standard perk. Any minutes you don't use "roll over," banking them to use later, like on a rainy day when you're really bored and just want to sit on the phone for hours. You pay for 1400 minutes a month, but only talk for 950. Those leftover 450 minutes are added to your general pool of minutes, so you'd have 1850 to use the following month. The net effect is that you're legitimately buying the minutes, in the same way you purchase a 12-pack of soda for $5.
If AT&T is going to count bytes like minutes, you should get rollover bytes. If you pay for 2 gigs of data, you should get 2 gigs of data. If you only use 500 megabytes that month, the leftover 1.5GB should rollover to the next month. Particularly since there's no middle ground between the two new plans—there's a massive gulf, 1000 percent wide, between 200MB and 2GB. So a lot of iPhone users are stuck, since they use somewhere between 200MB and 2GB of data—not skimpy enough to grab the cheaper $15-a-month plan, but not anything approaching 2GB. (A $20 500MB plan would be dead on for most iPhone owners, I think—which is probably why it doesn't exist.)
Rollover data would make AT&T's argument that the new plans are about value—not simply strangling the most hardcore data users taxing the network—way more convincing, since it would make the plans address the issue of network capacity in a tangible way.
Unfortunately, it's highly unlikely that AT&T is particularly interested in fairness, or at least in the idea of you actually using all the data you pay for. AT&T senior VP of data and voice products Mark Collins' response about why they're charging $20 extra for the privilege of tethering says it all:

That capability is enabling something you can't do today. You can use one device and get multiple connections so it's more useful to you. You're going to use more data so the price is based on the value that will be delivered. [emphasis mine]

That doesn't make any sense at face value, because you're paying for every byte of data you consume, and the tethering fee doesn't give include additional data—it comes out of the 2GB you're already paying for. The subtext is that AT&T doesn't actually expect most people to use that 2GB, and in fact, they don't want you to—which is they make it more expensive to make it easier to use.
Look, I'll pay per byte. Just give me all the bytes I pay for.

• Multitasking.
• Spell check (like on the iPad).
• Bluetooth keyboard support (again, on the iPad).
• User-defined wallpaper (a jailbreak favorite).
• Tap to focus when recording video, just like with photos, and a 5x digital zoom for the camera.
• Playlist creation and nested playlists.
• App folders for sorting apps! You can even put an app folder in the dock.
• Enhanced Mail! You can have a merged inbox view, switch between inboxes quickly, and sync to more than one Exchange account. There's also threaded messaging (at last!) and in-app attachment viewing.
• iBooks, just like on iPad, only smaller. You can wirelessly sync books between platforms, a la Kindle.
• Enterprise features, including remote device management and wireless app distribution.
• Game Center. It's like Xbox Live, but for iPhone games. Includes achievements, leaderboards, and match making. It will be available as a "developer preview," and out for consumers later this year.

• New SDK, available today.
• 1,500 new APIs.
• Background audio (think Pandora).
• Background VoIP (think Skype).
• Background location data, both with live GPS for backgrounded turn-by-turn, and cell tower-based for lower power draw.
• Local notifications. Like push notifications, but sends a notification straight from the app without needing a push notification server, perfect for an alarm, for instance.
• Fast app switching. Saves the state of an app and resumes it from where you left off, without dwelling in memory.
• iAd. Apple says it's for keeping "free apps free." The ads keep you in the app, while also taking over the screen and adding interactivity -- using HTML 5 for video -- up to simple gaming in-ad. Apple will offer a 60 / 40 split on revenue, and users can even buy apps straight from an ad.
• In-app SMS.
• Map overlays.
• Quick look for previewing documents.
• Photo Library access.
• Calendar access.
• Full access to the camera.
• Video playback and capture.
• Date and address "data detectors."
• Automated testing and performance / power analysis (the same tools Apple uses).

For this week's Photoshop Contest, I asked you to design some dream iPad apps. Some of these are legit and feasible, others are pipe dreams and the rest are flat-out insane.
