Sony's upcoming Android tablets sure haven't been publicity-shy

For products which still haven't been officially announced, Sony's upcoming Android tablets sure haven't been publicity-shy. Sony first teased us about them back in April. And on Wednesday, it held press events in New York and San Francisco at which it showed them off and released more details, such as the fact that the smaller S1 will be available exclusively in a version for AT&T's HSPA+ network -- although not full specs, or pricing, or a shipping timeframe other than "later this year."
I attended the West Coast edition of the sneak peek. When I see new tablets these days, I'm continuing to reflexively ask the question "Why should somebody buy this instead of an iPad?" It's too early to come to any firm conclusions about the Sonys, but both pass the obvious-differences-from-Apple's-tablet test.
The S1 is a 9.4" model with a wedge shape that angles the screen for comfy typing and feels like a folded magazine. (It's a major departure from every other current tablet -- but it does remind me of theoriginal 2007 version of Amazon's Kindle.)

The smaller S2, meanwhile, stretches the definition of "tablet" a bit. It's a clamshell device with two 5.5" displays which, in unfolded mode, can operate independently or as one big screen. It's reminiscent ofAcer's Iconia and Toshiba's experimental Portege, but the hinge makes more sense on the S2: the screens are small enough that a folded-shut unit will fit in a pocket. (Try that with your iPad.)
On the software side, Sony is going through a fair amount of effort to make these tablets stand apart from the Android herd. They both have a feature called Quick View which is designed to load Web pages much faster than the standard Android browser. (For what it's worth, it worked in Sony's demo.) They're also designed for extra-responsive scrolling, and are PlayStation-certified devices that can play some older PlayStation games, and will come with Sony's Reader e-book store and Qriocity movie and music services. The S1 includes a universal remote feature (which leverages the built-in IR port) and Sony is working with Adobe to help developers build Adobe AIR apps that make good use of the S2's twin screens.

AT&T on Wednesday said it plans to sell a version of the S2 (which, by the way, is a codename) "later this year." This new version of the S2 will be able to access AT&T's 4G network, in addition to Wi-Fi. People interested in the S2 will be able to purchase it with monthly data plans, though pricing for those plans wasn't revealed.
As with the 4G HP TouchPad announced Tuesday, 4G in this case doesn't mean Long Term Evolution, it means HSPA+. AT&T plans to launch five LTE markets this summer, with perhaps another 10 markets following by the end of the year. Since AT&T does not advertise the speeds it offers through its HSPA+ network, we can only assume that it will offer speedy networks in the areas AT&T says include "enhanced backhaul." Best guess?

Apple's new iCloud service doesn't fully launch until the fall alongside iOS 5

While Apple's new iCloud service doesn't fully launch until the fall alongside iOS 5, the company has already rolled out a few small portions of the service to existing users. Among the additions are automatic downloads and listings of purchased content for easy redownloading. 


Automatic downloads allow users to set preferences to have newly-purchased content such as music, apps, and books automatically pushed to other devices. Users have individual control over the three different media types and can also specify whether or not content pushing should be limited to Wi-Fi connections only in order to save cellular bandwidth. Settings are available within the "Store" menu of the Settings application in iOS 4.3. 


Facilitating the re-download of previously purchased content are new "Purchased" listings found in the iTunes, App Store, and iBooks applications for iOS devices. The new listings provide users with easy access to listings of all items purchased on a given Apple ID, whether or not that content is currently on the device. Users can then easily obtain the previously-purchased content not currently installed. 
What about those who share their iTunes account with their family members? Any way to control what gets downloaded?
Apple is also in the process of releasing iTunes 10.3 for Mac OS X and Windows, an update that should bring the new iCloud capabilities to the Mac side of things. The new version is being advertised on Apple's iTunes site, but the actual download page is still showing iTunes 10.2.2 and Software Update is not yet offering the new version.

How to create MAC services with specialized behaviors

Apple offers a number of its own services—like one that supports dictionary lookup on a selected word—that work with the platform's standard applications. Third-party developers can also create services to deploy with their applications. Automator makes it really easy for regular end users to create their own services with specialized behaviors.
As a Linux refugee, one of the features that makes Automator particularly compelling is that it allows me to integrate command-line operations, commands, and pipelines into my Automator workflows. In this tutorial, I'm going to show you two of the ways that I use shell scripting in Automator services in order to simplify my work.

A trivial example

I write virtually all of my articles in the Vim text editor and use Markdown syntax for formatting. On Linux, I used a Markdown processing tool from the command-line to convert my articles to HTML and then piped the output into the xclip command so that I could just paste the finished article directly into Ars Technica's content management system. I had a simple shell script that I could call directly from within Vim itself to perform those steps.
This same approach is still viable on Mac OS X, but I wanted to explore a more Mac-native solution to the same problem. More importantly, I wanted a solution that wasn't tied solely Hp 530 batteries,Hp dv1000 battery to Vim. That's where Automator comes into play. I built a trivial service that wraps a command-line Markdown processor. I can select a block of editable text with Markdown formatting in any Mac application and use the Markdown service to convert it to HTML in place.
To create a service, you start by selecting New from Automator's File menu. Automator will show you a list of available templates and prompt you to choose one for your new project. You should select the Service option, which is accompanied by a gear icon. In your new service, you will see a bar at the top of the Automator flow pane. It has combo boxes that allow you to set filters that establish the conditions in which your service should be made accessible. You want to make a service that receives selected text and will operate in any application.
Below those combo boxes is a checkbox that you can toggle to specify whether you want the output of your service to replace the selected text block. We definitely want that to be checked for our Markdown service, because we are replacing the Markdown-formatted input text with the HTML output provided Hp dv2000 batteries,Hp dv6000 battery by the Markdown processing engine.
The behavior of our Markdown workflow is really simple, so it will only require one action. From the left-hand action library pane, drag the Run Shell Script action out into the workflow pane. It will automatically create a connection with the top bar, indicating that it will use the user's selected text as the initial input.
The shell script action has a few simple options. You can choose the shell environment that you want to use for the operation and you can choose how you want it to handle the input. For the purpose of this example, we want to use the standard Bash shell. We also want to configure the action to pass the input into stdin, the UNIX standard input stream. This is a really useful capability in Automator, because it makes it possible to seamlessly mix Automator workflows with shell pipelines.
In the main text area of the shell action, we need to specify what command-line expression we want Bash to execute. In this case, all we want it to do is run the markdown command. I have already installed the markdown command using the relevant Homebrew package, but Automator's Bash shell doesn't seem to find it in my command path. To work around Automator's difficulty finding the command, I simply put the full path Hp dv6500 battery,Touch Screen Monitors into the text box, as you can see below.
Now that the workflow is complete, you just have to save it under the name Markdown. By default, Automator will store your custom services in the ~/Library/services directory. Any Automator service that is copied into that path will be made available through the services menu under applicable conditions. To run the new service, you just have to select some text and then click the Markdown item in the services menu.
