Lets consider positive and negative sides of tablets.
First positive side is the device is compact, has Internet connection, so your mailbox and interesting webpages always near.
For example you need a web site and live in Miami. So you can go to browser and enter professional web design company or miami web design.
Second side is it is possible to read books on it, so it is absolutely optional to get the electronic book. You can read it anywhere you want.
The third one is it is possible to listen to music, audiobooks and to watch movies film fans of course will be able to note video player existence.
Also it is possible to watch the location, the Google cards, using it as GPRS replacement. For example you found the professional web development company VizualTech and want to look where it is, you enter it™s adress 20900 NE 30th Ave. Aventura, Florida 33180 in your browser and watch card how to get there.
You always can synchronize important data with the main computer and to have them near hand.
Certainly, all these advantages are indisputable, but it is possible to note a little but which confuse. It should be noted that the tablet isn't capable yet of full-fledged multitasking. Personal computer and the laptop will allow you to open at once some various programs and appendices, to transfer information from one to another and so on.
The tablet provides only simulate a multitasking substitute, you will be able to open only 2 applications on the screen divided into two parts.
The software for a tablet, as a rule, carries out the same functions, as PS for the computer, but in strongly cut down option. So if you are a web designer who live in Miami (for example) it will be difficult to draw web design on tablet.
Work with additional devices with tablet is also difficult, difficult settings wait for you, installation special software and other difficulties.
All these and some other nuances which will be shortly eliminated. But for now the tablet hardly will be able to replace the computer. It doesn't mean that the tablet is worse than the computer, tablets allow to do simple and necessary work in the most convenient place for you.
So if you are web designer or website developer it will be more comfortable for you to use laptop at least in the next couple years.
