You can typically do all of the following on your tablet:
Most support WiFi.
You can use Skype, and if you have a built-in webcam you can use Skype to make a vedeo call.
You can send and receive emails.
You can browse the web and you can view flash websites.
You can play YouTube videos and some will play ripped DVDs.
You can view Pdf files.
You can view and edit MSWord, Powerpoint, and Excel files.
There more than 80,000 applications that you can download from Android and a great many of them are free.
You can increase the storage capacity by inserting a micro SD card, or flash USB device, if your tablet has a USB port. If your tablet has an extra memory slot/socket you can insert another card/stick of RAM to upgrade it.
If you do your calibration using a stylus, you may find your touch and scroll works more easily. The stylus makes it easier to pinpoint more accurately.
The screen typically works on a hold down system. Hold down on files and you can cut, rename, etc. Hold down on an empty spot on the screen pane and a menu will appear for you to paste, etc.
To remove an icon is quite simple. All you do is hold down the icon until a bin appears, then you move it over and hover it over the bin.
You can use single screen panes or multiple screen panes if you want to load several applications and then scroll between them.
Looking after your battery is probably one of the more important things you can do. Preferably dont let it run completely flat before you recharge. Lithium batteries do not have a memory and their lives are shortened by constantly doing this. Replacement batteries are not always easily available or simple to replace.
Apart from keeping the length of your battery life to the maximum, you will soon appreciate the sheer convenience of keeping your battery fully charged. The very portability of your tablet means that it is essential that your battery lasts and doesnt leave you stranded without power at an awkward time.
Save your battery and make your computer faster by turning off whatever non-essential applications you are not currently using. You may lose a little function, but the advantages usually outweigh the disadvantages. A one-click task killer can help you do this quickly and easily.
Talking about screen brightness, consider not leaving it on the default full brightness, but adjust it to what you need, depending on the environment in which you are working, and no more.
Instead of using power off choose hibernate and save the power your tablet will use for booting up.
