There are times when you may want to capture what is currently being shown on your iPad's screen. That’s easy to do on an iPad.

Simply press the Home button and then the Sleep/Wake button simultaneously. When you hear a click, the screenshot has been taken. You can then go to the photos gallery to see all of your captured screenshots.

The big difference between Android and the iOS is the fact that, on an Android device, you can play Flash videos. There are times however when this seeming advantage can be a disadvantage as Flash (such as Flash ads) can slow down your browsing experience or even crash your browser. There is a solution.

You can turn off Flash if you choose to. Simply go to your Browser's Settings by pressing on the Menu/Options button, then go to Advanced and change 'Enable plug-ins' setting from "Always on" to "On demand." Flash applications will now appear as an arrow that you must touch to start.

If you own an Android phone, you can use it as a substitute for an external drive or a USB key. You can load files into your phone simply by plugging it in to a PC with a USB cable, then tapping on “Mount” when you are prompted by the system.

This mounts the internal storage of the device as an external drive relative to the PC, and you can easily drag and drop files or create folders on the device as you see fit. Of course, it is recommended you do this on the SDCard that likely came with the device, or one that you buy for your phone.

If you are using Windows Gadgets (or those small mini-applications that are embedded on your desktop that show interesting things like the latest news, weather updates, or sports scores), you may sometimes wish you can just quickly hide them to declutter your workspace.

In Windows 7, you can do just that. Simply right-click on the desktop, go to View, and then clear the check mark on Show desktop gadgets. This will hide the gadgets. If you want to bring them back, just restore the check mark again.

Have you ever sent an email and then immediately regretted sending it? If you are using Gmail as your mail client, you can do just that with an interesting but buried option in Gmail settings.

To enable this feature, go to Mail Settings in Gmail (upper right corner, under the gear icon). Navigate to the "Labs" tab. In the labs search box, look for "Undo Send" and choose Enable, then save. Now in Mail Settings you will see an option to "Undo Send: Send cancellation period: __ seconds." Enter the number of seconds that Gmail will allow you to change your mind in the future (try 10 seconds).

With this enabled, the next time you send an email, you’ll be able to “Cancel” it from being sent out, as long as it is within the time frame you specified.

Facebook has become one of the main ways people communicate. You can post on people's Walls or send them messages using Facebook Messenger. This, in and of itself is pretty impressive, but what's lacking is the ability to call people directly from Facebook Messenger. With the number of people accessing Facebook from their phones nowadays growing more than accessing via a browser, this feature is highly requested.

In early January Facebook announced that they had started testing free calling to contacts over Facebook Messenger. This feature was tested in Canada for all users with an iPhone, and turned out to work well. So, in late January Facebook rolled this out to iPhone users in the US as well.

This new service uses VoIP (Voice over Internet Protocol) technology, commonly found in many business's phone systems, to offer users in Canada and the US the ability to call other Facebookers using the Messenger app for free.

Calls can be made via your data connection or over Wi-Fi on your iPhone. No love for Android as of yet, but we are sure it's coming soon. If you use the Facebook Messenger app, you should be able to use it now. You can call other users by:

1. Opening the app (or download, install and open it from here) and find the person you would like to call.
2. Tapping on their name to start a conversation.
3. Pressing the "i" button in the top right of the conversation windows and selecting Free Call.

Will businesses benefit? It's hard to say whether businesses will find this feature useful at this time. If your employees use iPhones, and are often in an area with poor cell service but a decent data connection, this is a free way to stay in touch.

This could also prove a good way to deal with public complaints on your Facebook page. You could encourage the person to take the complaint offline and talk to them, as long as you both have an iPhone.

In reality however, most businesses will likely not use this feature at this time. However, there is a good chance that Facebook will release more business oriented calling features in the future which could give you another way to contact clients.

What do you think? Will you or your employees use this feature? Let us know, and if you have any questions about VoIP, please contact us today.

Did you know that on iOS5 on the iPad, you can actually split the keyboard into two? This can be useful for typing with your thumbs if you are holding the iPad with both hands.

To do so, press and hold the keyboard icon on the on-screen keyboard. An option will appear, allowing you to split the keyboard into two. Alternatively you can drag the keyboard icon up across the screen until the keyboard splits up. Still another way is to simply put two fingers around the center of the keyboard and simultaneously drag them apart in a splitting motion.

Want to do a quick currency conversion? You can use Google for that. Simply type in the amount in the original currency, then the currency you want to convert it to.

For example, type in: "100 dollars in yen" or "100 dollars in Mexican Pesos" and check out the results. If you have a mobile data plan on your mobile phone with a browser, you can use this tip for quick currency conversions on the go.

The Mac introduced the concept of using multiple "Desktops" (previously called "Spaces") using Lion's Mission Control application. Using Mission Control, you can specify which desktop applications will automatically open in which desktops by default.

To set your preferences, select and right-click (or ctrl+click or two-finger click) on an application in the Dock, then select the "Options" menu in the resulting pop-over. Inside that menu, links appear that allow you to remove the app from the Dock, open it at Login, or to have it Show in the Finder app. If you have multiple desktops active, an additional set of options will appear at the bottom. Here you can "assign" the app to "This Desktop" or the current active desktop, or to open in "All Desktops" or "None." Make your selection and your app will now open in the specific Desktop or Desktops you specify on launch.

If you use an iPad, there is a switch conveniently located at the right side of the device which you can set to either lock the orientation of the screen or to mute the audio when you slide the switch—depending on your preference.

To set your preference, go to Settings > General, and under the "Use Side Switch" section, choose either "Lock Rotation" or "Mute."
