in that you are right ;=)
even with my busiest domain I come merely 1GB....

but these are numbers! And that is the competition!
They offer fantastico, install support, Joomla / Mambo / WordPress communities etc. and they help to move with scripts and databases, and as I pointed out, I never experienced so fast support
the performance is good, the servers are stable etc.

that's why I am so satisfied with them
