Is this board a good alternative to the PC?

Hi,
I have seen the board described in this link.

I think that its a good solution to realize an embedded system with VGA
output, in that cases where, to use the PC, is not convenient.
I have seen that it's available also a dev kit to develop the code in C++
and it is not necessary to use an operating system.
How is it possible to work with a system without operating system?
C++ Standard allows two implementations: hosted and stand-alone. A hosted
implementation lives on and under control of, an operating system. The
other kind, a stand-alone implementation, is essentially an operating
system by itself. Just like any other embedded system that takes some
input and produces some output, a compiler can be made stand-alone.
You thing thought of it? Is it really a good product? Who has used this
board?
