'Note to self: Call Jane in the morning regarding Tuesday's conference call.' We've all made little mental notes like this, many of which we will forget about. Traditionally, we would write the reminder down on a sticky-note, or in a daytimer. But now, you can use your mobile device to record the note. If you have an Android tablet, there are some neat apps that can help store your thoughts and notes.

Here's three note apps that different users will find useful:

Google Keep For users who are integrated with Google; using Google Drive, Gmail, etc., Keep is a recently released note app that allows you to create notes and lists. You can also attach voice reminders, pictures and change the color of each note.

What separates this app from others is that it syncs your notes automatically with Google Drive, which means you can access, edit and manage the notes from any system. The mobile app looks great, as it follows Google's new 'clean' look with lots of white space. Notes are added to the main screen as thumbnails with the main content featured in the image. If you use Google's apps, this is a great addition that you will likely find useful. Free on Google Play.

OneNote Mobile If your office uses Microsoft Office, or Office 365, you may have already used OneNote. The mobile version lets you create notes and lists with bullet points, checkboxes, text and pictures. You can sync these notes with your SkyDrive account, or your Office 365 ID - they should both be the same ID - and have access to them on nearly every device including your desktop.

If you use OneNote on your desktop or browser, you will be able to view and open these notes using the mobile app and vice versa. Free for 500 notes on Google Play. If you want to create more than 500 notes, there is an in-app upgrade cost that varies depending on your account.

Evernote If you use multiple mobile and desktop platforms, or aren't picky about an app's integration with existing systems, Evernote should be right up your alley.

Like Google Keep, this app lets you create notes and lists, and also add voice reminders and pictures. The ability to search your notes for keywords is also included, which makes this app useful if you take a large quantity of notes.

The key distinguishing feature of this app is that it isn't just for one system. You can install versions on nearly every platform e.g., iOS, Windows Phone, BlackBerry, Windows, Mac, Linux, Chrome, Firefox, etc. And your notes will be synced as long as you have an Internet connection. This makes it perfect for the business owner who has a Windows PC in the office, an iPhone and an Android tablet. Free on Google Play.

These are just three potential note apps that you can use on your Android tablet. Do you use other ones? Let us know.

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.

Do you prefer Bing over Google but like Google's sparse but fast loading page better? With this tip you can get the best of both worlds.

As users of Bing know, when you visit the home page of Bing, a page with a featured photo as the background is displayed by default, which increases the load time of the page. This can be distracting or annoying—especially if you have a slow connection. Disable this photo from loading by simply bookmarking this URL (http://www.bing.com/?rb=0). The next time you visit Bing, the photo will not appear.

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."
