Computer systems

Hints and tips

• Equipment reviews in magazines can be helpful, if a bit technical. Occasionally they produce beginners' sections or supplements aimed at small business or home office users.
• PCs can have a range of energy saving features, some more effective than others. Check manufacturers' claims if environmental concerns are important to the business.
• Portable computers (or laptops) can now be as capable as desktop models, but always cost more for similar specifications.
