For years, a great way that IT professionals have saved money was to purchase a very powerful server computer and very low end client computers. They would then set up the client computers to use a virtual environment that was powered by the server. This allows for a company to only have to focus on investing in a high-end server and the clients can be relatively cheap.
This same idea can be applied to using a Asus Transformer tablet while connected remotely (using Teamviewer) to your high-end desktop computer. This way you can leverage the speed and storage of your desktop with the functionality and portability of your Asus prime.
This is one of the many areas that a tablet is useful as we find a place for it in our productive lifestyles.
