This meant that a single lineup could have machines tailored to match the price and performance niches that formerly demanded entirely separate computer systems. This flexibility greatly lowered barriers to entry. With most other vendors customers had to choose between machines they might outgrow or machines that were potentially too powerful and thus too costly. In practice, this meant that many companies simply did not buy computers. Now, a customer could purchase a machine that solved a particular requirement, knowing they could change the models as their needs changed, without losing support for the programs they were already running.
